The EA waits for TP or SL to trigger and then opens a position in the opposite direction. It checks if there are sufficient funds before sending a transaction request. OnTrade Trading.

For example, we have an open buy position. Once Take Profit or Stop Loss is triggered, a new sell position is opened. Then, after triggering TP or SL, open a new buy position.

Transaction ends in " Online Transaction ":
