+# Bitcoin Accumulation Zone Monitor — Architecture & Logic
+
+## Overview
+
+This is **NOT** a trading bot or ML predictor. It monitors proven Bitcoin on-chain metrics that have historically signaled optimal accumulation (buying) zones for long-term holders. Each metric scores 0-10 points, producing a composite score of 0-100.
+
+**Philosophy:** Every signal is transparent and traceable. No black box. The metrics used have correctly identified every major Bitcoin cycle bottom since 2010.
+
+## How It Works
+
+### Data Pipeline

+
+### Data Sources
+
+All data is scraped or fetched from free sources — **no API keys required**.
+
+| Source | Method | Data |
+|--------|--------|------|
+| LookIntoBitcoin / BitcoinMagazinePro | Playwright browser scraping of Plotly Dash charts | Puell Multiple, MVRV Z-Score, Reserve Risk, RHODL Ratio, NUPL, 200W SMA, LTH Realized Price, LTH Supply, Hash Ribbons, Pi Cycle |
+| alternative.me | Free REST API | Fear & Greed Index (daily, back to Feb 2018) |
+| CoinGecko | Free REST API | BTC price, market cap, 24h change |
+
+#### Scraping Method (LookIntoBitcoin)
+
+The site uses Plotly Dash charts. We intercept the `_dash-update-component` XHR response which contains the full chart data as JSON:
+
+```python
+page.on("response", handler)  # Intercept XHR
+page.goto("https://www.lookintobitcoin.com/charts/puell-multiple/")
+# Response contains: response['chart']['figure']['data'] → list of trace objects
+# Each trace: {name: str, x: [dates], y: [values]}
+```
+
+This gives us the **complete historical time series** (5000+ data points per metric going back to 2010) without needing any API key.
+
+## Scoring System
+
+### Individual Metrics (0-10 each)
+
+#### 1. Fear & Greed Index (source: alternative.me)
+Measures market sentiment from social media, surveys, and momentum.
+
+| F&G Value | Classification | Score |
+|-----------|---------------|-------|
+| 0-10 | Extreme Fear | 10 |
+| 11-25 | Fear | 7 |
+| 26-45 | Neutral-low | 4 |
+| 46-55 | Neutral | 2 |
+| 56-75 | Greed | 1 |
+| 76-100 | Extreme Greed | 0 |
+
+**Logic:** "Be fearful when others are greedy, be greedy when others are fearful." — Buffett. Extreme Fear has historically coincided with cycle bottoms.
+
+#### 2. Puell Multiple (source: LookIntoBitcoin)
+Measures miner revenue relative to 365-day average. When miners earn very little (low Puell), they're capitulating — historically a bottom signal.
+
+| Puell Value | Meaning | Score |
+|-------------|---------|-------|
+| < 0.3 | Deep miner capitulation | 10 |
+| 0.3-0.5 | Miner stress | 8 |
+| 0.5-0.8 | Below average revenue | 5 |
+| 0.8-1.2 | Normal | 3 |
+| 1.2-2.0 | Above average | 1 |
+| > 2.0 | Miner euphoria | 0 |
+
+**Historical accuracy:** Puell < 0.5 identified the Dec 2018, Mar 2020, and Jun 2022 bottoms.
+
+#### 3. MVRV Z-Score (source: LookIntoBitcoin)
+Compares market value to realized value. Negative Z-Score means the market is valued below what everyone paid — extreme undervaluation.
+
+| Z-Score | Meaning | Score |
+|---------|---------|-------|
+| < 0 | Below realized value | 10 |
+| 0-0.5 | Undervalued | 8 |
+| 0.5-1.5 | Fair value | 5 |
+| 1.5-3.0 | Overvalued | 2 |
+| 3.0-5.0 | Very overvalued | 1 |
+| > 5.0 | Extreme overvaluation | 0 |
+
+**Historical accuracy:** Every time MVRV Z-Score went below 0, buying led to >200% returns within 2 years (100% hit rate across all cycles).
+
+#### 4. Drawdown from ATH (calculated from price)
+How far BTC has fallen from its all-time high. Larger drawdowns = better buying opportunity historically.
+
+| Drawdown | Score |
+|----------|-------|
+| > 70% | 10 |
+| 50-70% | 8 |
+| 30-50% | 6 |
+| 20-30% | 4 |
+| 10-20% | 2 |
+| < 10% | 0 |
+
+#### 5. Price vs 200-Week SMA (source: LookIntoBitcoin)
+The 200-week moving average has historically acted as the absolute floor in bear markets.
+
+| Position | Score |
+|----------|-------|
+| Below 200W SMA | 10 |
+| 0-20% above | 6 |
+| 20-50% above | 3 |
+| 50-100% above | 1 |
+| > 100% above | 0 |
+
+#### 6. Reserve Risk (source: LookIntoBitcoin)
+Measures the confidence of long-term holders relative to the price. Low Reserve Risk = high confidence among HODLers + low price = excellent time to buy.
+
+| Reserve Risk | Score |
+|--------------|-------|
+| < 0.002 | 10 |
+| 0.002-0.005 | 7 |
+| 0.005-0.01 | 4 |
+| 0.01-0.02 | 2 |
+| > 0.02 | 0 |
+
+#### 7. RHODL Ratio (source: LookIntoBitcoin)
+Ratio of 1-week old coins to 1-2 year old coins. Low ratio = long-term holders dominating (accumulation). High ratio = short-term speculation (distribution).
+
+| RHODL | Score |
+|-------|-------|
+| < 100 | 10 |
+| 100-500 | 7 |
+| 500-2000 | 4 |
+| 2000-10000 | 1 |
+| > 10000 | 0 |
+
+#### 8. NUPL — Net Unrealized Profit/Loss (source: LookIntoBitcoin)
+Shows what fraction of market cap is unrealized profit. Negative = market is at a loss (capitulation). Above 0.75 = euphoria.
+
+| NUPL | Phase | Score |
+|------|-------|-------|
+| < 0 | Capitulation | 10 |
+| 0-0.25 | Hope/Fear | 7 |
+| 0.25-0.5 | Optimism | 4 |
+| 0.5-0.75 | Belief/Greed | 1 |
+| > 0.75 | Euphoria | 0 |
+
+#### 9. LTH Realized Price vs Spot (source: LookIntoBitcoin)
+Long-Term Holder Realized Price = average cost basis of coins held >155 days. When spot price drops below this, even diamond hands are underwater — extreme value.
+
+| Position | Score |
+|----------|-------|
+| Price below LTH RP | 10 |
+| 0-20% above | 6 |
+| 20-50% above | 3 |
+| > 50% above | 1 |
+
+#### 10. Hash Ribbons / Miner Capitulation (source: LookIntoBitcoin)
+When miners capitulate (hash rate declining), it signals maximum pain. The recovery signal (hash rate resuming growth) has been a reliable buy signal.
+
+| Signal | Score |
+|--------|-------|
+| Active buy signal | 10 |
+| Recent recovery | 6 |
+| Normal | 3 |
+| Miner euphoria | 0 |
+
+### Composite Score
+
+```
+Total Score = Sum of all individual metric scores (0-100)
+```
+
+| Score Range | Assessment | Action |
+|-------------|------------|--------|
+| 85-100 | Extreme Accumulation Zone | Strong buy — historically rare, ~4x per decade |
+| 70-84 | Strong Accumulation | Buy — excellent long-term entry |
+| 55-69 | Moderate Opportunity | Consider buying — decent entry |
+| 40-54 | Neutral | Hold — not compelling either way |
+| 25-39 | Caution | Reduce or wait — market heating up |
+| 0-24 | Extreme Caution | Do NOT buy — historically the worst times |
+
+## Backtest Engine
+
+### Purpose
+Reconstruct the composite score historically and compare against actual BTC forward returns to validate the scoring system's accuracy.
+
+### Methodology
+
+1. **Historical Reconstruction:** Using scraped historical data (2010-present), calculate what each metric's score would have been on every day
+2. **Forward Returns:** For each historical day, calculate what BTC actually returned over the next 30, 90, 180, and 365 days
+3. **Score Bracket Analysis:** Group days by score bracket and calculate average forward returns, win rates, max drawdowns
+4. **Recency Weighting:** More recent cycles weighted higher because BTC's cycle-over-cycle returns diminish as it matures:
+   - 2022-present: 4x weight
+   - 2020-2021: 3x weight
+   - 2018-2019: 2x weight
+   - Before 2018: 1x weight
+5. **Cycle-Separated Results:** Returns shown per cycle (Cycle 3: 2016-2019, Cycle 4: 2020-2023, Cycle 5: 2024+)
+
+### Diminishing Returns Adjustment
+
+Bitcoin's gains decrease every cycle. A score of 90 in 2018 led to different outcomes than a score of 90 in 2022:
+- The backtest separates results by cycle
+- Current expectations are based on the 2 most recent comparable cycles
+- Adaptive thresholds recalculate based on rolling 2-year windows

-# BTC ML Trading Strategy Optimizer
+# Bitcoin Accumulation Zone Monitor

-An automated optimization loop that trains ML models on BTC/USDT data, backtests trading strategies, and uses an LLM to iteratively improve the configuration.
+> Bitcoin on-chain metrics dashboard with classic equal-weight scoring, ML-optimized scoring, historical backtesting, and click-to-select metric context for long-term BTC accumulation decisions.
+
+![Dashboard](screenshots/dashboard-main.png)
+
+## What It Does
+
+Monitors Bitcoin accumulation conditions using 16 scored market/on-chain indicators plus optional informational cycle metrics. Each scored metric receives a 0-10 score and rolls into a 0-100 accumulation score.
+
+The dashboard now supports two scoring modes:
+
+- **Classic** — transparent equal-weight scoring across every active metric.
+- **ML** — feature-importance weights trained against historical 365-day forward returns, with displayed per-metric weights and point contributions.
+
+Historical backtests show score-vs-price behavior, score bracket performance, major signal events, and current-score context. Metric cards are clickable: selecting a metric overlays its historical series on the score chart and shows comparable historical periods with forward returns.
+
+## Screenshots
+
+### Main Dashboard — ML mode + metric context
+![Main Dashboard](screenshots/dashboard-main.png)
+*Live BTC price, Classic/ML scoring toggle, 16 active scored metrics, ML weights/contributions, metric sparklines, and click-to-select historical context.*
+
+### Historical Backtest
+![Backtest](screenshots/dashboard-backtest.png)
+*Current signal percentile, comparable historical periods by cycle, score-vs-BTC chart, bracket performance, and major signal events.*
+
+### Settings
+![Settings](screenshots/dashboard-settings.png)
+*LLM provider configuration for optional AI-powered signal commentary and local/cloud model selection.*
+
+## Feature Highlights
+
+- **16 scored metrics** from market sentiment, miner stress, valuation, holder behavior, network activity, and velocity signals.
+- **Classic vs ML scoring toggle** on the dashboard and backtest API.
+- **ML score explainability**: metric cards show learned weight and contribution in points.
+- **Leakage-resistant ML validation**: training uses purged time-series splits so 365-day forward-return labels do not overlap validation windows.
+- **Historical context panel**: compares the current composite score against historical periods and forward returns.
+- **Clickable metric cards**: select any metric to see percentile, similar historical levels, forward returns, example dates by market cycle, and highlighted chart periods.
+- **Score history chart** with BTC price overlay, range controls, and selected-metric overlay.
+- **Backtest dashboard** with current signal context, score bracket performance, and signal-crossing events.
+- **Quick vs full refresh**: quick refresh updates BTC price and Fear & Greed; full refresh re-scrapes on-chain sources.
+- **LLM settings UI** for Ollama, LM Studio, OpenAI, Anthropic, and OpenRouter.
+
+## Metrics
+
+| # | Metric | Source | Accumulation Signal |
+|---|--------|--------|-------------------|
+| 1 | Fear & Greed Index | alternative.me API | Extreme fear / capitulation sentiment |
+| 2 | Puell Multiple | LookIntoBitcoin | Miner revenue stress |
+| 3 | MVRV Z-Score | LookIntoBitcoin | Market near/below realized value |
+| 4 | Drawdown from ATH | Calculated from BTC price | Deep correction from cycle high |
+| 5 | Price vs 200W SMA | LookIntoBitcoin + BTC price | Price near/below long-term trend |
+| 6 | Reserve Risk | LookIntoBitcoin | High holder confidence relative to price |
+| 7 | RHODL Ratio | LookIntoBitcoin | Long-term holder dominance |
+| 8 | Net Unrealized Profit/Loss (NUPL) | LookIntoBitcoin | Capitulation / early recovery zones |
+| 9 | LTH Realized Price | LookIntoBitcoin | Price near long-term holder cost basis |
+| 10 | Hash Ribbons | LookIntoBitcoin | Miner capitulation/recovery signal |
+| 11 | SOPR | CheckOnChain | Spent outputs near loss / reset territory |
+| 12 | Sell-side Risk Ratio | CheckOnChain | Low realized profit/loss pressure |
+| 13 | Active Address Momentum | CheckOnChain | Network activity momentum extremes |
+| 14 | Transaction Count Momentum | CheckOnChain | Transaction activity momentum extremes |
+| 15 | NVT Price | CheckOnChain | Network-value valuation discount/premium |
+| 16 | VDD Multiple | CheckOnChain | Coin-days/velocity reset conditions |
+
+Informational cards may also appear when data is available, such as **Long-Term Holder Supply** and **Pi Cycle Bottom**. These are displayed for context and are not included in the composite score.
+
+## Score Interpretation
+
+| Score | Assessment | Interpretation |
+|-------|-----------|----------------|
+| 80-100 | 🟢 Extreme Accumulation Zone | Broad capitulation/value conditions across active metrics |
+| 65-79 | 🟢 Strong Accumulation Zone | Historically attractive long-term entry territory |
+| 50-64 | 🟡 Moderate Opportunity | DCA-friendly, but not maximum-signal conditions |
+| 35-49 | 🟡 Neutral | Mixed signals; not compelling either direction |
+| 20-34 | 🔴 Caution — Overheated | Market conditions becoming less favorable |
+| 0-19 | 🔴 Extreme Caution | Historically poor accumulation setup |
+
+Backtest tables provide actual historical forward-return statistics per score bracket, including 30d/90d/180d/1yr averages, win rate, max gain/loss, and average max drawdown.
+
+## ML-Optimized Scoring
+
+The ML mode uses a `GradientBoostingClassifier` trained on historical feature rows to predict whether a day was a good long-term buy based on 365-day forward return. Training features include:
+
+- Classic metric scores.
+- Raw metric values.
+- 30-day metric deltas.
+- Interaction features such as MVRV × NUPL and Puell × Reserve Risk.
+- Cycle-position context such as days since ATH.
+
+The resulting feature importances are aggregated back into transparent metric weights stored in `config/ml_weights.json`. The UI displays normalized weight and contribution for each active metric.
+
+Validation uses purged expanding time-series splits: because each label uses a 365-day forward-return window, training rows whose label windows overlap validation are removed before scoring validation folds.
+
+## Tech Stack
+
+| Component | Technology |
+|-----------|-----------|
+| Backend | Python 3.13 + FastAPI |
+| Frontend | Inline HTML/CSS/JS dark trading-terminal UI |
+| Charts | Chart.js |
+| Scraping | requests + Playwright-style browser scraping where needed |
+| Data APIs | alternative.me, CoinGecko, LookIntoBitcoin, CheckOnChain |
+| ML | NumPy + pandas + scikit-learn GradientBoostingClassifier |
+| Process Manager | pm2 or uvicorn |
+| Default Port | 3088 |
+
+## How Data Is Collected
+
+Data is collected from free/public sources and cached locally under `data/`.
+
+- Fast live refreshes update BTC price, ATH/drawdown, 200D SMA/Mayer where possible, and Fear & Greed.
+- On-chain metrics are cached and reused because they update slowly.
+- Full refresh re-scrapes on-chain metrics from LookIntoBitcoin/CheckOnChain.
+- Historical backtest data lives in `data/history.json` and supports charting, backtests, and metric-context lookups.
+- Score history appends to `data/score_history.jsonl`.

+```
+
+## Reproducible Setup
+
+Install [uv](https://docs.astral.sh/uv/) and use Python 3.11-3.13. Dependencies are declared in explicit `runtime`, `ml`, and `dev` groups in `pyproject.toml`; exact cross-platform resolutions are committed in `uv.lock`.
+
+```bash
+git clone <repository-url>
+cd btc-accumulation-monitor
+uv sync --locked --group runtime --group ml --group dev
+```
+
+Install the Chromium binary once for full on-chain refreshes. Keep its path explicit so installation and runtime use the same browser cache:
+
+```bash
+export PLAYWRIGHT_BROWSERS_PATH="$PWD/.playwright"
+uv run --frozen playwright install chromium
+```
+
+`requirements_vps.txt` is a lock-derived, hash-pinned compatibility export for pip-based hosts. `pyproject.toml` and `uv.lock` remain authoritative; regenerate the compatibility file after dependency changes with:
+
+```bash
+uv export --frozen --no-dev --group runtime --group ml \
+  --no-emit-project --no-header --output-file requirements_vps.txt
+```
+
+## Running
+
+The executable launcher fixes `PYTHONPATH`, preserves an explicitly supplied `PLAYWRIGHT_BROWSERS_PATH`, and starts port 3088 from the locked environment:
+
+```bash
+./scripts/run.sh
+```
+
+Equivalent exact command:
+
+```bash
+PLAYWRIGHT_BROWSERS_PATH="$PWD/.playwright" PYTHONPATH=. \
+  uv run --frozen --no-dev --group runtime --group ml \
+  python -m uvicorn dashboard.server:app --host 0.0.0.0 --port 3088
+```
+
+Then visit `http://localhost:3088`.
+
+## Container Deployment
+
+The image uses a multi-architecture Python base, installs Playwright Chromium and its OS libraries during the build, and runs the application as non-root UID `10001`. Compose publishes port 3088, restarts unless stopped, and persists `/app/data` and `/app/config` in named volumes.
+
+```bash
+docker compose build
+docker compose up -d
+```
+
+The Docker and Compose healthchecks probe `GET /health/live`. The deployment must include the reliability revision that supplies that endpoint; without it, Docker correctly reports the container unhealthy even if the older application server is accepting requests.
+
+Named volumes are initialized from the image on first use. Back up both before replacing or deleting them:
+
+```bash
+docker volume inspect btc-accumulation-monitor_btc-monitor-data
+docker volume inspect btc-accumulation-monitor_btc-monitor-config
+```
+
+For bind-mounted deployments, ensure the host directories are writable by UID `10001` and do not replace `config/` with an empty directory.
+
+## First Run and Data Freshness
+
+1. Visit `http://localhost:3088` for the dashboard.
+2. Use **Quick Refresh** for price and Fear & Greed updates while retaining cached slow-moving on-chain metrics.
+3. Use **Full Refresh** when on-chain source data must be re-scraped; this requires the installed Playwright Chromium browser and external source availability.
+4. Visit `http://localhost:3088/backtest` for historical analysis.
+5. If historical data is missing, populate `data/history.json` through the existing collection flow.
+
+Freshness is metric-specific. Price and sentiment APIs can update frequently, while public on-chain chart sources commonly update daily and may be reused from cache. A successful refresh is not proof that every upstream metric has a new observation. Check source timestamps/status exposed by the running revision, and treat missing, stale, or scrape-failed metrics as unavailable rather than silently current. `data/` is operational state and should be persisted and backed up.
+
+## ML and Backtest Caveats
+
+ML weights and backtest output are research artifacts, not investment advice or evidence of future performance. Any reported ML result must retain its provenance: source-data snapshot/range, feature and label definitions, training window, purge/embargo policy, code revision, dependency lock, random seed (when applicable), and generated weight/config artifact.
+
+Model selection and threshold tuning must use training/validation data only. Report final performance on a genuinely untouched out-of-sample (OOS) period; do not describe in-sample fit, cross-validation used for selection, or the best result from repeated experiments as OOS. Forward-return labels require purging overlapping label horizons, but purged cross-validation alone does not create an untouched final test set. Results without reproducible provenance and a reserved OOS evaluation should be labeled exploratory.
+
+## Useful API Endpoints
+
+| Endpoint | Description |
+|----------|-------------|
+| `GET /api/data?mode=classic` | Current metrics using equal-weight scoring |
+| `GET /api/data?mode=ml` | Current metrics using ML-optimized weights |
+| `GET /api/history` | Recent live score history |
+| `POST /api/refresh` | Quick refresh |
+| `POST /api/refresh?full=true` | Full on-chain refresh |
+| `GET /api/backtest?mode=classic` | Historical backtest with classic scoring |
+| `GET /api/backtest?mode=ml` | Historical backtest with ML scoring |
+| `GET /api/metric-context?metric=mvrv_zscore&mode=ml` | Similar historical levels and forward returns for one metric |
+| `GET /api/settings` | Safe LLM settings payload |
+
+## Testing and CI
+
+Run the committed test suite and the same static compilation gate used by Gitea Actions:
+
+```bash
+uv sync --locked --group runtime --group ml --group dev
+uv run --frozen python -m compileall -q \
+  dashboard scrapers scoring backtesting ml ml_engine llm_client scripts orchestrator.py
+uv run --frozen pytest
+```
+
+`.gitea/workflows/ci.yml` runs lock validation/install, static compilation, and tests for pull requests and pushes to `main`.

-```
-
-### 2. Windows PC
-
-```bash
-# From VPS — installs all ML deps on Windows via SSH
-bash scripts/setup_windows.sh
-```
-
-Or manually on Windows:
-```bash
-pip install -r requirements_windows.txt
-```
-
-### 3. Mac Mini
-
-Ensure Ollama is running with the qwen3.5:27b model:
-```bash

+
+## Core Question
+"Given current market conditions, is NOW a good time to BUY BTC for long-term holding?"
+
+## What the Model Does
+For each candle, the model predicts an Accumulation Score (0-100):
+- 90-100: STRONG BUY -- historically rare, excellent entry point
+- 70-89: GOOD BUY -- better than average entry
+- 50-69: NEUTRAL -- average time to buy
+- 30-49: WAIT -- price likely to come down
+- 0-29: POOR -- historically bad time to buy (near local tops)
+
+The model is trained on ACTUAL forward returns at 7d, 30d, and 90d horizons, weighted 20/30/50. Times when buying led to the best long-term returns get the highest scores.
+
+## Primary Metric: cost_basis_improvement_pct
+This measures how much better the model's average buy price is vs uniform DCA.
+- 10%+ = good
+- 15%+ = excellent
+- 20%+ = exceptional
+Also require strong_buy_signal_count >= 30 for statistical validity.

 ## Config Parameters You Can Modify

-**model_type**: "xgboost", "lightgbm", "catboost", or "ensemble"
-  - xgboost: Generally best for structured data, fast GPU training
-  - lightgbm: Faster training, good with large feature sets
-  - catboost: Handles feature interactions well, less tuning needed
-  - ensemble: Combines all three, reduces variance but slower
+**model_type**: "xgboost", "lightgbm", "catboost", "lstm", or "hybrid"
+  - hybrid: Average of LSTM + XGBoost regression predictions. Recommended default.
+  - xgboost: Fast GPU training, good for structured features.
+  - lstm: Captures temporal patterns in price sequences.

-**hyperparameters**:
-  - learning_rate (0.001-0.3): Lower = more robust but slower. If overfitting, decrease.
-  - max_depth (3-10): Controls model complexity. Deeper = more overfitting risk.
-  - n_estimators (100-2000): More trees = better fit but diminishing returns.
-  - subsample (0.5-1.0): Row sampling. Lower = more regularization.
-  - colsample_bytree (0.5-1.0): Feature sampling per tree. Lower = more diversity.
-  - min_child_weight (1-20): Higher = more conservative splits.
-  - gamma (0-5): Minimum loss reduction for split. Higher = more pruning.
-  - reg_alpha (0-10): L1 regularization. Encourages sparsity.
-  - reg_lambda (0-10): L2 regularization. Prevents large weights.
+**hyperparameters** (gradient boosting):
+  - learning_rate (0.001-0.1): Lower = more robust. Start conservative.
+  - max_depth (3-8): Controls complexity. Deeper risks overfitting.
+  - n_estimators (200-1500): More trees = better fit but diminishing returns.
+  - subsample (0.5-1.0): Row sampling for regularization.
+  - colsample_bytree (0.5-1.0): Feature sampling per tree.
+  - min_child_weight (5-30): Higher = more conservative (important for noisy targets).
+  - gamma (0-5): Minimum loss reduction for split.
+  - reg_alpha (0-10): L1 regularization.
+  - reg_lambda (1-10): L2 regularization. Higher values prevent overfitting.
+
+**hyperparameters** (LSTM):
+  - lstm_hidden_size (32-256): Hidden units.
+  - lstm_num_layers (1-4): Stacked layers. 2 is usually optimal.
+  - lstm_dropout (0.1-0.5): Regularization.
+  - lstm_epochs (50-200): Max training epochs (early stopping usually triggers).
+  - lstm_batch_size (32-128): Smaller = noisier but better generalization.
+  - lstm_sequence_length (15-60): Past candles the LSTM sees. Longer = more context.
+  - lstm_patience (5-20): Early stopping patience.

 **target**:
-  - direction: "long" or "both"
-  - horizon_candles (1-20): How far ahead to predict. Longer = smoother but lagging.
-  - threshold_pct (0.3-3.0): Minimum move % to label as positive. Higher = fewer but clearer signals.
+  - forward_periods_4h: List of 3 forward periods in 4h candles [short, medium, long].
+    Defaults: [42, 180, 540] = roughly [7d, 30d, 90d]
+  - weights: Weights for each period. Default [0.2, 0.3, 0.5] (emphasize long-term).
+  - score_range: [0, 100] -- do not change.

 **strategy**:
-  - entry_threshold (0.5-0.8): Min prediction probability to enter trade. Higher = fewer trades, higher quality.
-  - stop_loss_pct (0.5-5.0): Max loss before exit. Tighter = more stopped out.
-  - take_profit_pct (1.0-10.0): Target profit. Should be > stop_loss for positive expectancy.
-  - trailing_stop_pct (0.5-3.0): Trailing stop distance. Tighter = locks profit faster but exits early.
-  - min_confidence_to_trade (0.5-0.9): Absolute minimum confidence to consider.
-  - exit_type: "trailing_stop" or "fixed" (just SL/TP)
+  - strong_buy_threshold (70-95): Score above which = STRONG BUY signal. Higher = fewer but better signals.
+  - good_buy_threshold (50-80): Score above which = GOOD BUY. Used for cost basis comparison.
+  - poor_threshold (10-40): Score below which = POOR time to buy.

 **features**:
-  - use_volume_features (true/false): Volume features can be noisy in crypto.
-  - use_candle_patterns (true/false): Candle patterns may or may not help.
-  - use_lag_features (true/false): Lagged features capture momentum.
-  - lag_periods: List of lag periods [1,2,3,5,10]
-  - lookback_periods: List of lookback windows [3,5,10,20]
+  - use_price_position (true/false): Distance from ATH, 52w high/low, percentile.
+  - use_momentum (true/false): RSI, MACD, Stochastic, Williams %R, ROC.
+  - use_volatility (true/false): Bollinger Bands, ATR, consecutive red candles, drawdown.
+  - use_volume (true/false): Volume ratio, OBV, red/green volume ratio.
+  - use_cycle (true/false): MA cross regime, candles since major drawdown.
+  - use_pca (true/false): PCA dimensionality reduction.
+  - pca_variance (0.80-0.99): Variance to retain.
+  - use_scaler (true/false): StandardScaler. Critical for LSTM.

 **training**:
-  - walk_forward_windows (3-10): More windows = more robust but less data per window.
+  - rolling_window (true/false): Rolling vs static walk-forward.
+  - rolling_train_size (1500-5000): Training window candles.
+  - rolling_test_size (100-500): Test window candles.

-## Key Metrics to Optimize (in priority order)
-1. **Sharpe Ratio** (target: > 2.0): Risk-adjusted return. Most important metric.
-2. **Profit Factor** (target: > 1.5): Gross profit / gross loss.
-3. **Max Drawdown** (target: > -15%): Worst peak-to-trough decline.
-4. **Win Rate** (target: > 55%): Percentage of winning trades.
-5. **Trade Count**: Need enough trades for statistical significance (>50).
+## Key Metrics to Analyze
+1. **cost_basis_improvement_pct**: PRIMARY metric. How much better is model buy price vs DCA.
+2. **strong_buy_signal_count**: Must be >= 30 for validity. Too few = raise threshold. Too many = lower it.
+3. **signal_frequency_pct**: Should be 5-15%. If outside, adjust thresholds.
+4. **avg_score_at_actual_bottoms**: Should be high (>70). Model should recognize bottoms.
+5. **avg_score_at_actual_tops**: Should be low (<30). Model should avoid tops.
+6. **model_r2_score**: Regression fit quality. > 0.2 is decent for financial data.
+7. **per_window_cost_improvement**: Consistency across windows. Low variance = robust.

 ## Decision Guidelines
- If Sharpe < 1.0: The strategy is not working well. Consider larger changes.
- If Sharpe 1.0-1.5: Decent. Fine-tune hyperparameters and thresholds.
- If Sharpe 1.5-2.0: Good. Make small, targeted improvements.
- If Sharpe > 2.0: Very good. Be careful not to overfit.
- If win_rate < 0.50 but profit_factor > 1.5: Strategy relies on big wins — ok, tighten SL.
- If win_rate > 0.60 but profit_factor < 1.2: Many small wins but losses are too big — widen TP or tighten SL.
- If trade_count < 30: Not enough trades. Lower entry_threshold or min_confidence.
- If max_drawdown < -20%: Too risky. Increase regularization, tighten stop loss.
- If per_window_sharpe has high variance: Model is not stable. More regularization or simpler model.
- Check feature_importances: If top features make financial sense, good. If random features dominate, possible overfitting.
+- If cost_improvement < 5%: Strategy is barely working. Try: switch model type, enable all features, increase training window, lower good_buy_threshold.
+- If cost_improvement 5-10%: Decent. Fine-tune thresholds and hyperparameters.
+- If cost_improvement 10-15%: Good. Make targeted improvements -- focus on signal consistency.
+- If cost_improvement > 15%: Very good. Be careful not to overfit. Check per_window variance.
+- If signal_count < 30: Not statistically valid. Lower strong_buy_threshold, increase training data.
+- If signal_frequency > 20%: Too many signals = not selective enough. Raise threshold.
+- If signal_frequency < 3%: Too few signals. Lower threshold.
+- If score_at_bottoms < 60: Model is missing bottoms. More features, different model type.
+- If score_at_tops > 40: Model is not avoiding tops. More regularization.
+- If per_window has high variance: Model is unstable. Increase regularization, try hybrid.
+- Check feature_importances: price position features should dominate (distance from ATH, percentile).

Hermes AgentandClaude Opus 4.6 <<EMAIL>>	8fca6181d5	feat: per-metric historical exploration with click-to-select context - Click any metric card to see historical periods where it was at a similar level - Purple dot highlighting on chart shows matching periods - Metric overlay line plotted on chart (dashed purple) - Metric Context panel shows percentile, comparable days, avg forward returns, and historical examples from different market cycles - New /api/metric-context endpoint for per-metric similarity analysis - Backtest chart_data now includes per-metric raw values - score_day() returns raw metric values alongside scores - Fixed JS SyntaxError from broken inline onclick escaping (uses addEventListener) Co-Authored-By: Claude Opus 4.6 <<EMAIL>>	2026-06-28 22:49:15 +00:00
BizzleBotandClaude Opus 4.6	4647c596b3	feat: ML-optimized accumulation scoring with dashboard toggle Train GradientBoostedClassifier on 2,601 days of historical data (2018-2025) to find optimal metric weights for identifying the best long-term buying opportunities. Uses time-series cross-validation to prevent look-ahead bias. Key results: - pct_above_200w_sma: 50.7% weight (was 11.1% equal) - drawdown: 14.6%, lth_rp: 10.9%, rhodl: 8.9% - fear_greed demoted from 11.1% to 5.1% - nupl/mvrv nearly eliminated (0.7-1.8%) ML Strong Accumulation bracket: avg +210% 1yr (vs +176% classic) New files: ml/optimizer.py, config/ml_weights.json Modified: scoring/engine.py (score_all_ml), backtesting/engine.py (ml_mode), dashboard/server.py (Classic/ML toggle) Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>	2026-03-21 23:18:29 +00:00
BizzleBot	f1d38f9abb	fix: backtest chart auto-switches linear/log based on price range - Added time range buttons (30D/90D/6M/1Y/2Y/4Y/ALL) to backtest chart - Auto-detects: if price range spans >20x → log scale, else linear - Short ranges (30D-2Y) now show meaningful price movement instead of flat line - Zone backgrounds updated to match new thresholds (35/50/65) - Monospace font, better tooltips with zone labels - Chart properly destroys and recreates on range change	2026-03-21 23:00:46 +00:00
BizzleBot	fb590105ce	fix: preserve ATH/Mayer/200D SMA when CoinGecko rate-limits - ATH: fall back to cached value when fetch fails - 200D SMA: compute from history.json when CoinGecko blocks us - Mayer Multiple: derived from 200D SMA fallback - Drawdown: preserve cached value on ATH fetch failure - Fixes N/A Drawdown and -- header stats after quick refresh	2026-03-21 22:55:37 +00:00
BizzleBot	85e0a6839f	fix: backtest engine uses thresholds.json (single source of truth) Previously the backtest engine had hardcoded OLD thresholds that diverged from scoring/engine.py + config/thresholds.json. Now loads from thresholds.json directly, ensuring the chart matches the dashboard.	2026-03-21 22:42:37 +00:00
BizzleBot	ececd65a22	feat: interactive score history chart with time range selector + BTC price overlay - Time range buttons: 30D, 90D, 6M, 1Y, 2Y, 4Y, ALL - BTC price overlay on right y-axis (orange dashed line) - Accumulation zone backgrounds (green/yellow/red shading) - Threshold lines at 65, 50, 35 - Tooltip shows score + zone label + BTC price - Uses backtest daily_scores for full history (not just score_history.jsonl) - Smart downsampling: daily for last 2yr, weekly before that - Chart height increased to 320px	2026-03-21 22:41:22 +00:00
BizzleBot	5538f666c5	fix: cycle-aware scoring thresholds for diminishing returns PROBLEM: Fixed thresholds based on 2015-2018 extremes meant the score could barely reach 65 in the current cycle. MVRV Z-Score bottoms are getting shallower (-0.6 → -0.4 → -0.3), Puell floors are rising, NUPL extremes are compressing. A 'good buy' in 2024+ looks different than 2018. SOLUTION: Widened scoring ranges across all metrics: - MVRV Z-Score: 0-1.0 now scores 8/10 (was 0-0.5) - Puell Multiple: 0.4-0.7 scores 8/10 (was 0.3-0.5) - NUPL: 0-0.3 scores 8/10 (was 0-0.25) - LTH Realized Price: 0-30% above scores 7/10 (was 0-20%) - 200W SMA: 0-30% above scores 7/10 (was 0-20%) - Drawdown: 40-60% scores 8/10 (was 50-70%) - Fear & Greed: 0-15 scores 10/10 (was 0-10) - RHODL: 0-200 scores 10/10 (was 0-100) RESULT: - Today: 75/100 Strong Accumulation (was 56) - Nov 2022 bottom: 91/100 (still extreme) - 2024-2026 now has meaningful signal variation - Each threshold has a note explaining the cycle compression logic	2026-03-21 22:35:13 +00:00
BizzleBot	6bfbd30e3d	fix: comparable periods pick one example per market cycle Instead of showing 5 recent days with similar scores (all from the same 2-week window), now picks one example per cycle: - pre-2016, 2016-17 Bull, 2018-19 Bear, 2020-21 Bull, 2022-23 Bear, 2024+ - Sorted by closest score match, then picks one per cycle - Shows cycle label in brackets next to each example - Much more representative of how the score performed across different eras	2026-03-21 22:21:14 +00:00
BizzleBot	6398c6c8f4	fix: main dashboard historical context shows all 4 timeframes (30d/90d/180d/1yr)	2026-03-20 23:32:30 +00:00
BizzleBot	22fc7fc6cd	fix: historical data stored permanently, only append new daily values - Historical data (5693+ points per metric) saved in history.json permanently - Quick refresh: only updates price + Fear & Greed from APIs (~2 seconds) - Full refresh: only needed for FIRST-TIME setup or if data is missing - Daily append: new values added to history.json from cache, not re-scraped - Startup: uses cached on-chain data if it exists, no unnecessary Playwright launches - On-chain metrics only update once per day, no reason to re-scrape them	2026-03-20 23:29:39 +00:00
BizzleBot	28b5240a81	perf: smart refresh — quick updates price/F&G only, full scrape every 6h - Quick Refresh button: updates price + Fear & Greed only (~2 seconds) - Full Refresh button: re-scrapes all on-chain data from LookIntoBitcoin (~2-3 min) - Background auto-refresh: quick every 15min, full only when on-chain data >6h old - Cached on-chain data preserved between quick refreshes - On-chain metrics only update daily anyway, no need to re-scrape every 15min	2026-03-20 23:25:54 +00:00
BizzleBot	e385765fda	add: 30d/90d/180d/365d forward returns in all backtest views - Bracket table now shows Avg 30d, 90d, 180d, and 1yr columns - Signal events show all 4 timeframes - Current context shows all 4 average returns - Comparable examples show all available timeframes - Updated backtest screenshot	2026-03-20 23:20:42 +00:00
