I'm a little bit busy right now , let me check by the weekend. I'm just learning mql programming, but I'll do my best try.

I think you just need to change OP_BUYSTOP to OP_BUYLIMIT, but I'm not checked well thow the EA works, may be you need to switch both Ordersend (instead OP_BUYSTOP use OP_BUYLIMIT), because for example if you want to pending trade above the price you only can put buystop or sellimit and viceversa.
