Can this EA be modify?

I understand what you want, but I don't think it has anything to do with RSI. The EA was purposely made to only open one order per candle. If this is removed, the conditions for more orders would exist on the same candle and there would be multiple orders open only minutes apart from each other. Is this what you want? 

I wouldn't like open by minutes, what about by pips.

Thanks again.

I wasn't saying I would add an extra condition to wait minutes between orders. I was simply saying that if the condition to wait until a new candle is removed, as you are asking for, the EA would make new orders in the same candle whenever it's existing order conditions are met. So what you would see is multiple orders being made within the same candle, sometimes only minutes away from each other. Not that I would add a requirement to wait minutes. Do you understand?
