What do you mean by "next candle close"?
If you want to open a trade in candle X and close it when that candle is closed, just use Once per bar -> Close trades. This means that any trade will be closed at the beginning of any candle.
If you want to open a trade in candle X and close it at the beginning of candle X+2... then I will suggest to try the Expiration settings. It's not exactly the same, it is similar, the trade would be closed at certain amount of time after its creation. If you still want to close is at the end/beginning of some candle, then I imagine using Once per bar followed by pink blocks For each Trade -> check age -> close
