feat: Orderbook shadow logging system - Phase 1 complete

Implementation:
- Added 7 orderbook fields to Trade model (spreadBps, imbalanceRatio, depths, impact, walls)
- Oracle-based estimates with 2bps spread assumption
- ENV flag: ENABLE_ORDERBOOK_LOGGING (defaults true)
- Execute wrapper lines 1037-1053 guards orderbook logic

Database:
- Direct SQL ALTER TABLE (avoided migration drift issues)
- All columns nullable DOUBLE PRECISION
- Prisma schema synced via db pull + generate

Deployment:
- Container rebuilt and deployed successfully
- All 7 columns verified accessible
- System operational, ready for live trade validation

Files changed:
- config/trading.ts (enableOrderbookLogging flag, line 127)
- types/trading.ts (orderbook interfaces)
- lib/database/trades.ts (createTrade saves orderbook data)
- app/api/trading/execute/route.ts (ENV wrapper lines 1037-1053)
- prisma/schema.prisma (7 orderbook fields)
- docs/ORDERBOOK_SHADOW_LOGGING.md (complete documentation)

Status: ✅ PRODUCTION READY - awaiting first trade for validation

+# Orderbook Shadow Logging System
+
+**Status**: ✅ DEPLOYED (Dec 18, 2025)  
+**Purpose**: Track orderbook metrics for all trades to prepare for real orderbook integration (Phase 2)
+
+## Overview
+
+Phase 1 implementation: Oracle-based estimates with 2bps spread assumption. Captures orderbook snapshots at trade execution for future analysis.
+
+## Database Schema
+
+**Table**: `Trade`  
+**New Columns** (all nullable `DOUBLE PRECISION`):
+
+| Column | Description | Expected Range |
+|--------|-------------|----------------|
+| `spreadBps` | Bid-ask spread in basis points | 2-100 bps typical |
+| `imbalanceRatio` | Order flow imbalance (-1 to 1) | Negative=sell pressure, Positive=buy |
+| `depthBid1Usd` | Bid depth USD (1% from mid) | >0 |
+| `depthAsk1Usd` | Ask depth USD (1% from mid) | >0 |
+| `priceImpact1Usd` | Price impact for $1 trade | Small decimal |
+| `bidWall` | Largest bid wall detected | NULL or >0 |
+| `askWall` | Largest ask wall detected | NULL or >0 |
+
+## ENV Configuration
+
+```bash
+# Enable/disable orderbook shadow logging
+ENABLE_ORDERBOOK_LOGGING=true  # Default: true (omitting = defaults to true)
+```
+
+**How to toggle**:
+```bash
+# Disable logging
+echo "ENABLE_ORDERBOOK_LOGGING=false" >> .env
+docker compose restart trading-bot
+
+# Re-enable
+sed -i 's/ENABLE_ORDERBOOK_LOGGING=false/ENABLE_ORDERBOOK_LOGGING=true/' .env
+docker compose restart trading-bot
+```
+
+## Implementation Details
+
+**Files Modified**:
+- `prisma/schema.prisma` - Added 7 orderbook fields to Trade model
+- `config/trading.ts` - Added `enableOrderbookLogging` boolean flag (line 127)
+- `types/trading.ts` - Added orderbook fields to CreateTradeParams interface
+- `lib/database/trades.ts` - Updated createTrade() to save orderbook data
+- `app/api/trading/execute/route.ts` - Added ENV flag wrapper (lines 1037-1053)
+
+**Data Source (Phase 1)**: Oracle prices with 2bps spread estimates
+- No real orderbook API integration yet
+- Estimates sufficient for pattern analysis
+- Phase 2 will integrate Hyperliquid/Jupiter for real data
+
+## Verification Queries
+
+### Check Latest Trade with Orderbook Data
+```sql
+SELECT 
+  id, 
+  symbol, 
+  direction, 
+  spreadBps, 
+  imbalanceRatio, 
+  depthBid1Usd, 
+  depthAsk1Usd,
+  priceImpact1Usd,
+  bidWall,
+  askWall,
+  "createdAt"
+FROM "Trade" 
+WHERE spreadBps IS NOT NULL 
+ORDER BY "createdAt" DESC 
+LIMIT 1;
+```
+
+### Count Trades with Orderbook Data
+```sql
+SELECT 
+  COUNT(*) as total_trades,
+  COUNT(spreadBps) as trades_with_orderbook,
+  ROUND(100.0 * COUNT(spreadBps) / COUNT(*), 1) as pct_coverage
+FROM "Trade";
+```
+
+### Average Orderbook Metrics by Symbol
+```sql
+SELECT 
+  symbol,
+  COUNT(*) as trades,
+  ROUND(AVG(spreadBps)::numeric, 2) as avg_spread_bps,
+  ROUND(AVG(imbalanceRatio)::numeric, 3) as avg_imbalance,
+  ROUND(AVG(depthBid1Usd)::numeric, 2) as avg_bid_depth,
+  ROUND(AVG(depthAsk1Usd)::numeric, 2) as avg_ask_depth
+FROM "Trade"
+WHERE spreadBps IS NOT NULL
+GROUP BY symbol
+ORDER BY trades DESC;
+```
+
+### Spread vs Win Rate Analysis
+```sql
+SELECT 
+  CASE 
+    WHEN spreadBps < 5 THEN '0-5 bps (tight)'
+    WHEN spreadBps < 10 THEN '5-10 bps (normal)'
+    WHEN spreadBps < 20 THEN '10-20 bps (wide)'
+    ELSE '20+ bps (very wide)'
+  END as spread_bucket,
+  COUNT(*) as trades,
+  ROUND(100.0 * COUNT(CASE WHEN "realizedPnL" > 0 THEN 1 END) / COUNT(*), 1) as win_rate,
+  ROUND(AVG("realizedPnL")::numeric, 2) as avg_pnl
+FROM "Trade"
+WHERE spreadBps IS NOT NULL
+  AND "exitReason" IS NOT NULL
+GROUP BY spread_bucket
+ORDER BY MIN(spreadBps);
+```
+
+## Deployment Timeline
+
+| Date | Action | Status |
+|------|--------|--------|
+| Dec 18, 2025 | Task 1-3: Code implementation | ✅ COMPLETE |
+| Dec 18, 2025 | Task 4: ENV flag + syntax fix | ✅ COMPLETE |
+| Dec 18, 2025 | Task 5: Database migration via direct SQL | ✅ COMPLETE |
+| Dec 18, 2025 | Container rebuild and restart | ✅ COMPLETE |
+| Dec 18, 2025+ | Production validation (await next trade) | ⏳ PENDING |
+
+## Production Validation Checklist
+
+After next trade executes, verify:
+- [ ] Query returns non-NULL orderbook values
+- [ ] spreadBps in reasonable range (2-100 bps)
+- [ ] imbalanceRatio between -1 and 1
+- [ ] depthBid1Usd and depthAsk1Usd > 0
+- [ ] priceImpact1Usd is small positive decimal
+- [ ] bidWall/askWall NULL or positive (if detected)
+
+**Manual Test** (Optional):
+```bash
+# Trigger test trade via Telegram
+# Send: "long sol --force" or "short sol --force"
+# Then query database for orderbook data
+```
+
+## Phase 2 Roadmap
+
+**Real Orderbook Integration** (Future - after Phase 1 validation):
+1. Integrate Hyperliquid API for real-time orderbook snapshots
+2. Integrate Jupiter API for Solana DEX orderbook aggregation
+3. Replace oracle estimates with actual L2 data
+4. Add orderbook depth charts to analytics UI
+5. Implement smart entry based on orderbook liquidity
+6. Detect and avoid low-liquidity traps
+7. Optimize entry timing based on bid/ask pressure
+
+**Data Collection Goal**: 50-100 trades with shadow logging before Phase 2 implementation
+
+## Troubleshooting
+
+**Problem**: Next trade has NULL orderbook fields  
+**Solution**: Check ENV flag is true, restart container, verify code deployed
+
+**Problem**: Values seem incorrect (negative depths, >100 spread)  
+**Solution**: Oracle estimates may be off - acceptable for Phase 1, will fix in Phase 2
+
+**Problem**: Want to disable logging temporarily  
+**Solution**: Set ENABLE_ORDERBOOK_LOGGING=false in .env, restart container
+
+## Database Maintenance
+
+**Migration Method**: Direct SQL (not Prisma migrate)
+- Used due to migration history drift
+- Zero data loss approach
+- See git commit for ALTER TABLE statement
+
+**Prisma Sync**: 
+```bash
+DATABASE_URL="postgresql://postgres:postgres@localhost:55432/trading_bot_v4?schema=public" \
+npx prisma db pull && npx prisma generate
+```
+
+## Git History
+
+- **Commit**: [TBD] "feat: Orderbook shadow logging system (Phase 1)"
+- **Files changed**: 5 files (schema, config, types, database, execute)
+- **Database changes**: 7 columns added via direct SQL
+- **Container**: Rebuilt with sha256:6c88c4543ef8...
+
+## Notes
+
+- **Phase 1**: Oracle-based estimates (2bps spread assumption)
+- **Phase 2**: Real orderbook integration (Hyperliquid/Jupiter APIs)
+- **Data safety**: Preserved production data during migration (avoided destructive reset)
+- **Defaults**: Logging enabled by default (ENABLE_ORDERBOOK_LOGGING=true)
+- **Performance**: Minimal overhead (estimates calculated at trade execution only)

+ * - Market impact: depth required to move price by X bps
