Reverse Orders

Hi, I would ask the programmers of this forum if I can change these 2 EA "Fx Prime2 hieken ashi.mq4" and "Heiken Ashi Bar Ea v1.0.mq4" working with this indicator Heiken_Ashi_Smoothed "so that open orders on the other hand ... so instead of BUY and SELL opens the contrary, I wonder why inverting only with OP_BUY OP_SELL wrong and I can not find what I need to change to make them work on the contrary, I thank you in advance.
