Help closing trades (learning MQL)

Hello,
I'm learning MQL and I'm stuck with a problem. It's simple but I'm just learning. I'd really appreciate the help.

I'm creating an EA that closes trades when prices reaches (in long) the last candle's low.
I'm trying to change this to do this when long (opposite when short):
- If price reaches current bar's low, then close trade (stop loss = current bar's low)
- If next candle closes positive with trade (that is blue in long, red in short), then close trade.
Can somebody help me?
Thanks in advance.

There you have it - you answered your own question. Set the order's stop loss to Low[0] or High[0], respectively..
The other answer is a bit more tricky. You can count the bars from the trade on (current bar having a count of 0) and when the counter reaches 2 it means that the future bar from back then, now passed to history. Now if a trade is still on, examine the relation between that bar's open and close (Open[1] vs Close[1]).
