No. But it's not necessarily the stop distance, it can also be a normal exit by a different algorithm. If algo A thinks you must buy long and algo B thinks 5 minutes later you must sell short, then a trade can be immediately closed. This is rare, but happens. The algos of Z12 interact and can close another algo's trades under some circumstances.

I can understand that this is not really optimal, but it's implemented this way in the system.
