To manage manual positions

Good morning developers, i need to develop a robot that manages  manual trading positions.

The open positions are in groups of 2 or 3 positions per pair, each position will initially have the same stop loss and different tp (tp 1, tp2 and tp 3). The expert will have to manage the positions in this way: when the first operation reaches the Tp (I'll call it tp 1) the robot will have to move the stop loss on the remaining 1 or 2 operations (depending on the case) to break even. This I will call strategy 1, in the future I would then like to implement the expert with other strategies that I will indicate later. For now it is necessary to implement the strategy 1.
