💡 What: This optimization refactors the trade execution logic within the MQL5 Expert Advisor to eliminate redundant `CopyBuffer()` calls. Indicator data (ATR, Donchian Bands) is now fetched once at the beginning of the `OnTick()` function and passed down as parameters to the `CalculateSL` and `CalculateTP` functions. 🎯 Why: The `OnTick()` function is a performance-critical hot path. In the original code, the `CopyBuffer()` function was called multiple times within the trade execution workflow for the same indicator data. This created unnecessary overhead on every tick. By fetching the data once and passing it down, we reduce the computational load, leading to more efficient execution. 📊 Impact: This change reduces the number of expensive `CopyBuffer()` calls within the `OnTick` function by up to three calls per trade signal. This results in a measurable performance improvement, allowing the EA to react faster to market changes, especially during periods of high volatility. 🔬 Measurement: The improvement can be verified by profiling the EA in the MetaTrader 5 Strategy Tester. A performance comparison between the original and optimized versions will show a reduction in the total time spent within the `OnTick` function. The code has also been successfully validated by the project's CI and test scripts. |
