Dear,
Would you like to open a new trade or invert the trade from buying to selling after a close position, is it possible?
You can do both thing. The question is, what do you want exactly to be done and when? I ask this because the answer will be different on a case by case basis.
I have a condition where he follows and makes the buy, but the market changes the direction and my condition identifies the change, I close the position and need to open a new position as a sell soon after.
the problem is that he is not opening the new trade after I close the position.
If you can easily identify when the change is done, then you just need to create a condition with it and then connect it to a close order block. Immediately after that, you can identify that closed trade on the 'on trade' tab and connect it to a buy/sell block as wished. The problem is if there are more than one buy so sell at the same time. Is that the case?
