## STEP 7 — TRADE HISTORY API

**Time:** 18:18:41 IST  
**Endpoint:** GET /paper/history  
**HTTP Status:** 200  
**Actual response (first 3 entries):**
```
{'trades': [
  {'symbol': 'BANKNIFTY', 'side': 'BUY→SELL', 'qty': 1, 'entry': 52050.0, 'exit': 52200.0, 'pnl': 150.0, 'time': '2026-06-30 18:18:40'},
  {'symbol': 'NIFTY', 'side': 'BUY→SELL', 'qty': 2, 'entry': 24320.0, 'exit': 24390.0, 'pnl': 140.0, 'time': '2026-06-30 18:18:39'},

## STEP 8 — DASHBOARD API

**Time:** 18:18:41 IST  
**Endpoint:** GET /dashboard/  
**HTTP Status:** 200

  "pnl": {"realized_pnl": 0.0, ...}
}
```
**Note:** Dashboard funds show 0.0 — this is because dashboard_service pulls from broker API (Angel One), not the paper engine. This is expected behaviour for paper trading mode.

---

## STEP 9 — RATE LIMIT TEST (H-2 FIX VERIFICATION)

**Time:** 18:18:41 – 18:18:43 IST  
**Test:** 6 rapid login attempts with wrong password from same IP

|---------|-------------|----------|
| 1 | 401 | Invalid password |
| 2 | 401 | Invalid password |
| 3 | 401 | Invalid password |
| 4 | 401 | Invalid password |
| **5** | **429** | **Too many login attempts. Try again in 60s.** |

✅ Rate limiter triggered at attempt 5 (limit = 5 per 60s). Fix H-2 confirmed working in production.

---

## STEP 10 — SELL-ON-NO-POSITION GUARD (H-10 FIX VERIFICATION)

**Time:** 18:18:43 IST  
**Test:** POST /paper/trade with SELL on WIPRO (no existing position)  
**HTTP Status:** 200  
**Actual Response:**
```json

```
✅ Guard confirmed working. No phantom short was opened. Fix H-10 verified.

## KNOWN ISSUES OBSERVED AT RUNTIME

None — no 500 errors, no crashes, no unexpected exceptions during the session.

**Limitations not caused by bugs:**
- 19 trade failures = capital management (correct)
- Dashboard funds = 0.0 (uses broker API, not paper engine — expected)
- WebSocket not tested via HTTP client (requires WebSocket protocol)
