- Added MIN_SIGNAL_QUALITY_SCORE_LONG and _SHORT fields to Settings interface
- Replaced single quality score field with three fields:
1. Global Fallback (91) - for BTC and other symbols
2. LONG Signals (90) - based on 71.4% WR data analysis
3. SHORT Signals (95) - based on toxic 28.6% WR data, blocks low-quality shorts
- Updated app/api/settings/route.ts GET/POST handlers to support direction-specific fields
- Fixed field naming consistency (MIN_SIGNAL_QUALITY_SCORE vs MIN_QUALITY_SCORE)
- User can now adjust direction-specific thresholds via settings UI without .env editing
- Container deployed: 2025-11-23T14:25:34 UTC
Settings UI was using wrong variable name (MIN_QUALITY_SCORE) while
code reads MIN_SIGNAL_QUALITY_SCORE. This caused quality score changes
in settings UI to have no effect.
Fixed:
- Settings API now reads/writes MIN_SIGNAL_QUALITY_SCORE
- Updated .env file to use correct variable name
- User's quality score increase to 81 will now work
Related: User increased min quality from 60 to 81 to filter out
small chop trades (avoiding -$99 trade with quality score 80).
- Add usePercentageSize flag to SymbolSettings and TradingConfig
- Add calculateActualPositionSize() and getActualPositionSizeForSymbol() helpers
- Update execute and test endpoints to calculate position size from free collateral
- Add SOLANA_USE_PERCENTAGE_SIZE, ETHEREUM_USE_PERCENTAGE_SIZE, USE_PERCENTAGE_SIZE env vars

- Remove signalQualityVersion and fullyClosed references (not in interfaces)
- Add comprehensive documentation in PERCENTAGE_SIZING_FEATURE.md
Benefits:
- Prevents insufficient collateral errors by using available balance
- Auto-scales positions as account grows/shrinks
- Maintains risk proportional to capital
- Flexible per-symbol configuration (SOL percentage, ETH fixed)
- Add ATR-based dynamic TP2 scaling from 0.7% to 3.0% based on volatility
- New config options: useAtrBasedTargets, atrMultiplierForTp2, minTp2Percent, maxTp2Percent
- Enhanced settings UI with ATR controls and updated risk calculator
- Fix external closure P&L calculation using unrealized P&L instead of volatile current price
- Update execute and test endpoints to use calculateDynamicTp2() function
- Maintain 25% runner system for capturing extended moves (4-5% targets)
- Add environment variables for ATR-based configuration
- Better P&L accuracy for manual position closures
**UI Updates (settings page):**
Added new '📈 Position Scaling' section with:
- Enable/disable toggle (defaults to OFF)
- Min quality score slider (60-90, default 75)
- Min profit to scale (0-2%, default 0.4%)
- Scale size percent (10-100%, default 50%)
- Max position multiplier (1-3x, default 2.0x)
- Min ADX increase (0-15, default 5)
- Max price position for scale (50-90%, default 70%)
**Visual Feedback:**
- Purple-themed section with warning banner
- Real-time risk calculator showing:
* Original position size (SOL example)
* Scale addition amount
* Total after 1 scale
* Maximum possible position size
- Dynamic descriptions explain each parameter
- Warning: 'DISABLED by default' with red indicator
**API Updates:**
Extended /api/settings GET/POST to handle 7 new fields:
- ENABLE_POSITION_SCALING
- MIN_SCALE_QUALITY_SCORE
- MIN_PROFIT_FOR_SCALE
- MAX_SCALE_MULTIPLIER
- SCALE_SIZE_PERCENT
- MIN_ADX_INCREASE
- MAX_PRICE_POSITION_FOR_SCALE
**User Flow:**
1. Navigate to http://localhost:3001/settings
2. Scroll to '📈 Position Scaling' section
3. Toggle 'Enable Position Scaling' to 1
4. Adjust thresholds (defaults are conservative)
5. See live calculation of scaling impact
6. Click 'Save Settings'
7. Click 'Restart Bot' to apply
**Safety:**
- Feature OFF by default (requires explicit opt-in)
- Warning banner explains scaling behavior
- Risk calculator shows maximum exposure
- Conservative defaults prevent aggressive scaling
- All parameters adjustable via sliders
**Example:**
With defaults (SOL $210×10x = $2100):
- Scale adds: $1050 (50% of $2100)
- Total after 1 scale: $3150
- Max position (2x): $4200
User can now enable and configure position scaling without touching .env file!
- Add SymbolSettings interface with enabled/positionSize/leverage fields
- Implement per-symbol ENV variables (SOLANA_*, ETHEREUM_*)

Defaults:
- SOL: 10 base × 10x leverage = 100 notional (profit trading)

- Global: 10 × 10x for BTC and other symbols
Configuration priority: Per-symbol ENV > Market config > Global ENV > Defaults

**Bug Fixes:**
- Fixed settings save failure by mounting .env file to container
- Added .env volume mount in docker-compose.yml
- Fixed permission issues (.env must be chmod 666)
**UI Changes:**
- Split TP controls into Price % and Size %
- TP1 Price: When to exit first partial
- TP1 Size: What % of position to close (1-100%)
- TP2 Price: When to exit second partial
- TP2 Size: What % of remaining to close (1-100%)
- Risk calculator displays dynamic percentages
**Example:**
- TP1 at +1% price, close 60% of position
- TP2 at +2% price, close 40% of remaining (24% of original)
- Total exit: 84% of position at TP levels
