Fix error in MT 5 Trailing EA and also provide me the same logic in MT 4 ( updated requirements 05/02/2026)

This project is based on an existing EA that trail behind.

1. Their is an issue with trailing based on lotsize

This should be corrected

current EA has 784 lines

Error

When option Enable Automatic Lot scaling is used, the trailing does not work correctly.

Lotscaling is done through another EA.

The EA does not trail then correctly anymore.

This option does not work correctly

2. Error in refresh of window, even when not order are open

3.Implement selection of Timeframe to 

Implement on Phase 4 the selectable timeframe M1/M3M5,M10,M15,M30,M60 (1h),M240(4h),Daily

4. The corrected EA should also be migrated to MT 4 trail on phase 4

Phase 4 is the trailing on the timeframe with distance behind.

This timeframe should be selectable 

M1/M3M5,M10,M15,M30,M60 (1h),M240(4h),Daily

Like seen on the M30 screenshot , Phase 4 only starts after the phase 3 has susccesfully closed
