Here is how to keep all orders at 20 pips away from the current price, but note that this is too aggressive, orders are modified on every tick and if you don't use some time filter the broker will hate you: https://fxdreema.com/shared/2R7PZiMed
I realized that I can't found make the opposite of "pips away from open price". I wanted to detect when the distance is lower than 19 pips, so I tried with negative values in "pips away from open-price", but nothing worked. As I created this block long time ago, I don't even remember how it should handle this 🙂
