@l-andorrà i dont really know how to create or implement a math code in fxdreema but thanks for your suggestion.

I did manage in the end to create a virtual trailing take profit which closes the trade partially. I used a condition where each new candle high above a specific price creates a small object on top of a candle high. The next condition is that the ma1, as well as each new created candle high should be above those created objects. If all conditions are true the trailing line will move a fixed distance from new candle highs.
