- Implements `CPositionManager` class in `ManagePositions.mqh` for robust Trailing Stop and Break Even logic. - Updates `SMC_TrendBreakout_MTF_EA.mq5` to use `CPositionManager` and exposes Scalping inputs. - Adds preset files for M5, M15, M30 scalping in `mt5/MQL5/Presets/`. - Documents strategy parameters in `docs/SCALPING_STRATEGY.md`. - Adds `scripts/research_scalping.py` utility.
