How should I set TimeInForce for different strategies?
TimeInForce determines how long a limit order stays open before automatic cancellation. The optimal setting depends on your trading style, market volatility, and desired execution speed.
🔹 Recommended Settings by Strategy
1️⃣ Scalping / High-Frequency Trading (HFT)
- TimeInForce: 10–30 seconds
Reason:
- Scalping and HFT strategies require instant execution
- Price moves quickly; stale orders can trigger at the wrong moment
- Short TimeInForce ensures trades are executed only when signals are fresh
Tip: Combine with a small AskPriceBufferPer (0.05–0.1%) to improve fill probability without introducing slippage.
2️⃣ Day Trading / Intraday
- TimeInForce: 30–120 seconds
Reason:
- Day traders can afford slightly longer order lifetimes
- Allows time for the market to reach your limit price
- Reduces missed trades in moderately volatile conditions
Tip: Adjust dynamically based on market liquidity and volatility.
3️⃣ Swing / Multi-Day Trading
- TimeInForce: 120+ seconds (or minutes)
Reason:
- Market moves slowly relative to your trade horizon
- Longer TimeInForce ensures limit orders are filled without requiring constant monitoring
Tip: Consider combining with wider AskPriceBufferPer to account for overnight or slow price swings.
🔹 General Guidelines
| Strategy Type | TimeInForce (seconds) | Notes |
|---|---|---|
| Scalping / HFT | 10–30 | Fast execution, minimize stale orders |
| Day / Intraday Trading | 30–120 | Balance execution time and signal relevance |
| Swing / Multi-Day | 120+ | Longer execution window, tolerate slower fills |
🔹 Practical Advice
Always match TimeInForce to market speed:
- Volatile markets → shorter times
- Calm markets → longer times
Combine with AskPriceBufferPer:
- Small buffer ensures fills without converting to market order
- Adjust buffer based on TimeInForce and strategy
Monitor fills and cancellations:
- If many orders are canceled too early, consider slightly increasing TimeInForce
- If trades are executed at outdated prices, shorten TimeInForce
✅ Key Takeaway
TimeInForce is a critical parameter for aligning execution with strategy goals:
- Short for fast, reactive strategies (scalping/HFT)
- Medium for intraday or day trading
- Long for swing/multi-day strategies
Correctly setting TimeInForce ensures your limit orders fill efficiently without executing at unintended prices, maintaining both precision and risk control.
