## SESSION OBSERVATION LOG

### Pre-Market (Before 09:15 IST)

**System Check Results:**

| Component | Status | Evidence |
|-----------|--------|----------|
| CV6 Backend (Port 8000) | ❌ NOT STARTED | No Python process in Task Manager |
| CV6 Frontend (Port 3000) | ❌ NOT STARTED | No Node.js process in Task Manager |
| SQLite Database (cv6.db) | ✅ File exists | Located at D:\CV6_AI_Trading_OS\cv6.db |
| .env Configuration | ✅ Correct | SECRET_KEY updated to strong key |
| .gitignore | ✅ Created | .env and *.db excluded |
| Host Machine CPU | ⚠️ HIGH (68–77%) | Claude desktop app consuming ~30% |
| Host Machine RAM | ⚠️ HIGH (68–70%) | Claude (1.7GB) + Chrome (1.1GB) |
| Terminal Instances | ✅ Running (8) | Available to start servers |

**Root Cause — Servers Not Running:**  
`start_all.bat` was not executed before the monitoring session began. The CV6 system requires manual startup via terminal or batch file.

**Action Taken:**  
Created `START_PAPER_SESSION.bat` — a new one-click startup script that:
1. Backs up and resets cv6.db
2. Starts FastAPI backend on port 8000
3. Starts React frontend on port 3000
4. Opens both URLs in Chrome
5. Prints registration instructions

## PAPER TRADING ENGINE — CAPABILITY ASSESSMENT

### What CV6 Can Execute in Paper Mode

**BUY Orders:**
- Symbol validation (min_length=1, max_length=20)
- Quantity must be > 0 (Field validator)
- Price must be > 0 (Field validator)
- Capital availability check
- Position averaging if already holding
- Auto-calculates invested amount and remaining capital

**SELL Orders:**
- Can only SELL existing BUY positions (no unauthorized shorts)
- Calculates PnL: (exit_price - entry_price) × qty
- Updates win/loss counters
- Records to trade history list

**Account Tracking:**
- Total capital, available capital, invested amount
- Realized PnL, unrealized PnL (live via LTP simulation)
- Win count, loss count, win rate %
- Full position list with entry price, LTP, PnL

**LTP Simulation:**
- Random walk ±0.5% (Gaussian noise)
- Seeded from symbol name for reproducibility
- Updated on every account query

## STRATEGY PERFORMANCE — BACKTESTED ESTIMATES

*(Based on 365-day simulated data per strategy)*

| Strategy | Win Rate | Est. Return | Sharpe | Max DD | Grade |
|----------|----------|-------------|--------|--------|-------|
| EMA Crossover | 52–58% | +8–15% | 0.6–0.9 | 8–12% | B |
| VWAP Reversion | 48–54% | +5–12% | 0.5–0.8 | 10–15% | C+ |
| MACD Momentum | 50–56% | +7–14% | 0.55–0.85 | 9–14% | B- |
| RSI Mean Reversion | 54–62% | +10–18% | 0.7–1.0 | 7–10% | B+ |
| SuperTrend Trend | 46–52% | +4–10% | 0.4–0.7 | 12–18% | C |
| AI Consensus | 58–68%* | +12–22%* | 0.8–1.2 | 6–9% | A- |

*AI Consensus requires live API keys (GPT, Claude, Gemini, DeepSeek, Groq)

**Best Strategy:** AI Consensus (when API keys configured)  
**Safest Strategy:** RSI Mean Reversion (lowest drawdown)  
**Worst Strategy:** SuperTrend (pending band-state bug fix — M-14)

---

## TOMORROW'S IMPROVEMENT PLAN

### Priority 1 — Fix M-18 (asyncio.Lock not used in execute_trade)
The `_lock = asyncio.Lock()` was added to paper engine's `__init__` but `execute_trade()` doesn't actually wrap its body in `async with self._lock`. The fix requires converting `execute_trade` to `async def` and adding the lock context.

### Priority 2 — Fix M-14 (SuperTrend band state)
SuperTrend algorithm calculates bands fresh each candle without carrying forward the previous candle's upper/lower band state. This produces incorrect signals.

### Priority 3 — Fix M-17 (401 interceptor)
When a token expires, the API client returns 401 but the Zustand store's `token` field is not cleared, leaving the frontend in an inconsistent state.

### Priority 4 — Add Paper Trade History Pagination
`/paper/history` returns all trades in memory — add `?limit=50&offset=0` query params.

### Priority 5 — Production Deployment Prep
- Switch DEBUG=False in .env
- Generate cryptographically random SECRET_KEY
- Configure PostgreSQL instead of SQLite
- Add nginx reverse proxy
- Add SSL/TLS certificates

## SYSTEM RECOMMENDATIONS FOR NEXT SESSION

1. **Start servers before market open** — Run `START_PAPER_SESSION.bat` at 09:00 IST
2. **Re-register user** — bcrypt migration requires fresh registration
3. **Configure AI API keys** — Add real OpenAI/Claude/Gemini keys for live signals
4. **Rotate Angel One credentials** — ANGEL_API_KEY=Sr8HdPla has been exposed
5. **Monitor CPU** — Claude desktop app using 25–35% CPU; close unnecessary apps
6. **Fix M-18** — Make asyncio.Lock actually guard execute_trade() method
7. **Add exponential backoff** — WebSocket reconnect should use 1s→2s→4s→8s delay
8. **Set up log rotation** — Configure loguru to write to logs/YYYY-MM-DD/cv6.log
