It still doesn't work and change SL only for the oldest trade. Do you have some other idea how can I solve it?

Hey!

I have one problem that I can not solve. The idea of my EA is to set mutual SL for opened trades if the ammount of trades is equal or larger than 3. I wanted to take SL value from bucket of trades (average open price - then it is BE for 3 open trades in equal fraction).

The main problem is that EA change SL for only the oldest trade. Do you have some ideas?
Custom TP changes to each opened trade. So the list of changes seems like this:
Trade 1. SL: SL taken from bucket of list, TP: value I provided
2. SL:0. TP: value I provided
3. SL:0. TP: value I provided
4. SL:0. TP: value I provided
