"Modify each trade" block
-
Just a small suggestion...
Its not immediately clear in the "Modify each trade" block that to leave the TP unchanged, the field should be left blank or at 0. Other blocks have a "no change" option.

-
This is one of the oldest blocks and I didn't updated it for months (I have no excuse for that). But "Start trades loop -> (in loop) Modify SL and TP" does the same.
-
I'd assumed that with conditions outside of a given group's trades loop I'd need to use this particular block. If group 2 = something, alter group 1, and so on.

Mmmm now I don't understand this

This block is like the combination I wrote above, only if it's output has to be connected with other blocks - in the combination this output goes from the yellow out of "Start trades loop" - this is the point where it goes after the loop is over.
