This commit implements several performance optimizations in the `SMC_TrendBreakout_MTF_EA.mq5` Expert Advisor:
1. **Lazy Account Info Retrieval**: Refactored `OnTick` to fetch `ACCOUNT_BALANCE`, `ACCOUNT_EQUITY`, and `ACCOUNT_MARGIN_FREE` only when a signal is confirmed and based on current risk settings. This significantly reduces terminal API calls.
2. **Local Fixed-Size Arrays**: Replaced `static` dynamic arrays with local fixed-size arrays for `emaFast`, `emaSlow`, and `atr` data. This avoids the overhead of dynamic memory management and `ArraySetAsSeries`.
3. **Redundant Calculation Removal**: Optimized `OpenBuyTrade` and `OpenSellTrade` by pre-calculating `slDistance` once and passing it to `CalculateTP` and `CalculateLots`.
4. **Optimized Function Signatures**: Updated `CalculateTP` and `CalculateLots` to accept only the necessary metrics and pre-calculated values.
These changes result in a leaner "hot path" and reduced overhead during trade execution.
