Strategy analysis
This EA is not a self-trading strategy but a stop-loss management utility. Its core mechanism reads the Parabolic SAR indicator values and automatically updates the stop-loss level of existing positions as the SAR moves favorably, thereby locking in floating profit. Entry conditions are not applicable since the EA does not open its own trades. Exit conditions manifest as the trailing stop level being progressively moved upward for longs or downward for shorts, eventually triggering a close when price retraces to the trailed stop. Position sizing is not involved as the EA only manages stop-losses of existing positions. Money management is indirectly supported through the trailing stop mechanism which protects account equity by preventing winning trades from turning into losers. The timer feature allows users to set activation and deactivation times, enabling the trailing stop to function only during specified trading sessions and avoiding unnecessary stop adjustments during low-liquidity or highly volatile periods.
Strengths
- Parabolic SAR-based dynamic trailing stop is more adaptive than fixed-pip trailing, adjusting to market volatility rhythm
- Timer functionality allows enabling/disabling trailing stop during specific sessions, adapting to different market phases
- Supports filtering by magic number and position number, enabling precise control over which positions to manage
- Supports both SAR-based and fixed-pip trailing modes, providing high flexibility
Weaknesses
- As a utility EA, it provides no autonomous trading signals, relying entirely on manual trade entry or other EAs for signals
- Parabolic SAR frequently reverses in ranging markets, potentially triggering stops prematurely and causing frequent small losses
- Does not account for spread and slippage impact on the actual execution price of the trailing stop
- Timer only supports hour-level settings, lacking finer minute-level time control
Possible improvements
- Add SAR signal confirmation filtering, such as combining ADX trend strength indicator to avoid frequent stop adjustments in ranging markets
- Support minute-level timer precision and allow setting multiple non-contiguous active time windows
Risk assessment
Overall risk: Low
- SAR frequent reversals in ranging markets may bring stops too close, increasing probability of being stopped out
- During timer-inactive periods, stops will not be adjusted, creating a protection gap if market moves sharply
