Here is one of my live FTMO EAs trading right now and showing the SL moved to breakeven. Note the red circle. The red dash is the original SL. It does not move because its price level is defined by the SL in points in the EA properties box. However, notice the red arrow, it is pointing at the new SL set at or near the original Buy price. So the orignal SL as defined in the properties box does not change. However, it is overridden in the EA’s coding such that the new SL takes priority.
Hope this helps clear up the confusion.
