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)
