- 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
