# TP/SL Evaluation Guide for OKX Contracts

## How to Evaluate a TP/SL Setup

### Step 1: Gather Data
- Entry price, current price, TP trigger, SL trigger
- Liquidation price (from position details)
- 7-day OHLCV data for the asset

### Step 2: Calculate Key Metrics

| Metric | Formula | Good | Bad |
|:---|:---|:---|:---|
| Risk:Reward | (TP - entry) / (entry - SL) | ≥ 1.5 | ≤ 1.0 |
| SL distance % | (entry - SL) / entry × 100 | > daily avg range | < daily avg range |
| SL vs Liquidation | SL price vs liq price | Wide gap | Close to liq |
| TP vs 7d High | Compare | Below 7d high | Above 7d high (needs breakout) |
| Breakeven win rate | 1 / (1 + R:R) | < 40% | > 50% |

### Step 3: Common Issues

**Issue: Stop loss too tight**
- Symptom: SL distance < asset's average daily range
- Example: 0.76% SL on an asset with 5% daily volatility
- Fix: Widen SL to at least 1.5× the daily ATR (Average True Range)

**Issue: TP unrealistic**
- Symptom: TP is above the 7-day high for longs
- Fix: Set TP within the recent range, or use trailing stop instead

**Issue: R:R too low**
- Symptom: Win/loss amount ratio ≤ 1:1
- Fix: Either widen TP or tighten SL (but not too tight!)
- Rule: With R:R of 1:1, you need >50% accuracy to profit. With 2:1, you only need >33%.

**Issue: SL at round number**
- Symptom: SL at exactly $1,000, $1,100, etc.
- Fix: Offset by 0.5-1% (e.g., $1,005 or $995) to avoid stop hunts

### Step 4: Report Template

## OKX-Specific Notes

- OKX OCO orders: TP and SL are paired — one triggers, the other cancels
- `tpOrdPx: "-1"` means market price execution on trigger (guaranteed fill but possible slippage)
- `slOrdPx: "-1"` same for stop loss
- `mgnMode: "isolated"` = only the margin amount is at risk (not cross-margin)
- `mgnRatio` < 1.0 means close to liquidation
- `uplRatio` is unrealized PnL as a fraction of margin (e.g., -0.024 = -2.4% of margin)
