I don't think that's the case. Trade is open when previous candle was bullish,which is obvious that close of that candle must be above low of the candle, otherwise it will be bearish candle.
Trade is open at specific time let's say 15:00 , when cadle ID is "1" takes data from candle printed at 14:45-15:00 . The fact my trade is open at 15:00 close price of previous candle is my open price and the fact is bullish candle it must be above the low. So how it's possible to be negative then ?
