This commit implements several performance optimizations for the `ExpertMAPSARSizeOptimized_Improved.mq5` Expert Advisor: 1. **OnTick Gatekeeper Optimization**: Added an early-exit 'new bar' check using the lightweight `iTime()` function at the very beginning of `OnTick`. This prevents expensive terminal API calls and logic from executing on every price tick when not required (when `Expert_EveryTick` is false). 2. **Event-Driven Statistics**: Relocated the expensive `UpdateDailyStatistics()` call, which performs history scanning, from the high-frequency `OnTick` path to the event-driven `OnTrade()` handler and a periodic `OnTimer()` handler (60 seconds). 3. **Startup Initialization**: Added an initial call to `UpdateDailyStatistics()` in `OnInit()` to ensure accurate statistics upon EA startup. 4. **Timer Management**: Enabled `EventSetTimer(60)` in `OnInit()` and added proper cleanup with `EventKillTimer()` in `OnDeinit()`. 5. **Efficient History Selection**: Refactored `UpdateDailyStatistics()` to use a specifically calculated `todayStart` timestamp for `HistorySelect()`, reducing terminal data retrieval overhead compared to the previous rolling 24-hour window. 6. **Redundancy Removal**: Removed an expensive and redundant `CopyRates()` call used for bar time tracking at the end of `OnTick()`. These changes significantly reduce CPU usage and terminal overhead, especially during high-volatility market conditions with rapid tick streams.
