Create "for each Trade" with the number of repeat cycles 1 and filter only Buy (Sell - in another block). Further, the indentation from the open price by X pips and open opposite orders (two blocks - 1 to flip Sell orders, the second - Buy).
Instead of one repeat, there is an infinite repeat.
It seems to me that incorrect execution occurs when adding an order type (Buy/Sell) filter).
