@meken I am not sure what result you will get from adjust on init, may give you half of constant and you need something like +50%, I will also say if you change the constant after inserting then the variable will stay the same as on int and you may as well make this value your constant, put constant & variable in comment block to visually check. For your buy/sell group you want to use numbers, this just adds to the magic number so needs to do somthing like 1111+1=1112, in your trail use the group that you have added to the 2nd BUY/SELL so it only responds to these trades, move all from on trade to on tick (if you reed the instructions trail needs to be here), you can use flags on trade with a purple trade closed block to activate trail. This is how I would do, hope this helps.
