Add a single pair recovery strategy to a multi-pair expert advisor

Within an existing expert advisor that works on misalignment between three related pairs, I would like to add a recovery strategy hedge / hedge the hedge to single trades in loss within the group of three. I have already tested this strategy with a separate expert, but has great limits; this addition should make sure that when the balance of the three trades including recoveries reaches a predetermined profit in terms of pips (that already exists in expert to edit) or a percentage of the balance (feature to be added), close all the basket in profit.
