@sktsec yeah I get that it is a event but I also notice there's similar functions outside the on trade tab aswel. I don't know if it is different if you use mlq4 or 5, but I notice using 5 using different tabs don't matter that much.
Also for big projects it is usefull to separate trees and functions but any other than that.

@floridabrazil You'd better contact the admin directly through the support page. He will answer you before two weeks.
