A trading approach that uses algorithms to execute a very high volume of trades in extremely short timeframes, often holding positions for seconds or less. HFTstrategies profit from tiny price movements across many rapid trades.
Why It Matters
- 1Nearly all prop firms prohibit high-frequency trading because it can exploit latency differences between the firm's simulated data feed and the real market.
- 2HFTon simulated accounts can produce unrealistic results that don't reflect genuine market conditions.
- 3Firms typically define HFTby metrics like minimum trade duration (e.g., trades must be held for at least 30-60 seconds) or maximum number of trades per day. Violating HFTrules is treated as market manipulation and results in account termination.
Example
- 1A trader programs a bot that opens and closes positions within 2-5 seconds, executing 200+ trades per day on a simulated prop firm account.
- 2Each trade captures 1-2 ticks of profit.
- 3While profitable on the simulated feed, these results rely on latency advantages that wouldn't exist in a real market.
- 4The firm's monitoring system flags the account for trade durations under 10 seconds.
Common Mistakes
- ✖Scalping legitimately but holding trades so briefly that the firm flags them as HFT
- ✖Not checking the firm's minimum trade duration requirements before starting
- ✖Assuming that fast execution from manual scalping won't trigger HFTdetection
