How to reverse an order

Hello the idea is simple and complicated at the same time. I got my ea doing a sell but I want it to do a buy at the same time it thinks in selling. Seems it can be done in just one ea, so I just would like to know if anyone knows of ways of doing this. As you see it´s not basically reversing ea logic but doing the opposite logic ea is supposed to do.

Reversal logic isn't always as simple as it looks. What you want to do is even simpler if you have the source code. Just change all OrderSend() OP_BUY to OP_SELL and vice versa.
