Specification

Hi, a modification of an existing EA, I don't know if it's possible.
If my EA enters a buy, then the EA must not under any circumstances take a sell.
And it's the same if EA enters a sell, then under some circumstances EA may take a buy.
But EA can have several trades that go in the same direction.
Is there anyone who can undertake to develop such an EA for me, I have the foundation,
so you don't need to develop it from scratch.
