Ok, your code is doing exactly what you want, what’s the issue?
The only issue I can detect (but you may even take it as an advantage) is that if your trade closes before the 15-minute entry candle does, another trade will open in the same direction because C1 will change only at the closing of the 15-minute candle. You may leave it as is, if that’s what you want, or you need some additional code to prevent entering further trades before the 15-minute candle closes.
