That question can foreign exchange trading affect your studies has a very simple answer which is if you(the trader)want it to.it implies that you the trader are the one to decide if it will affect your studies or not,like the saying goes, too much of everything is bad. If you do not devote the time you are supposed to be studying to your studies,then you are bound to fail,and equally,if you do not devote the time for your trade to it,you are bound to loose.
