Hi, how do I store and get the value of high and open price of previous closed candle since the value will keep changing on every previous closed candle? The idea is to get the High & open from a certain condition when the condition true store the value of Open and High. Technical term called as a pullback area. double high=0,open=0, AskPrice=MarketInfo(OrderSymbol(),MODE_ASK), BidPrice=MarketInfo(OrderSymbol(),MODE_BID); bool sellcondition = Open[1] > Close[1] && High[1] > Open[1] && Close[1] > Low[1]; if( sellcondition ) { open=Open[1]; high=High[1]; } if(Bid > open && Bid < high) { OrderSend(Symbol(),OP_SELL,0.01,BidPrice,3,0, 0,"",0,0,clrRed); }

If you declare your high and open as global scope or static variables and then will only assign values to them when your condition is met, then at any future bar, they will contain the High and Open values of the last time the condition has been met. For example, your code snippet can be modified as follows: static double high=0,open=0, AskPrice=MarketInfo(OrderSymbol(),MODE_ASK), BidPrice=MarketInfo(OrderSymbol(),MODE_BID); bool sellcondition = Open[1] > Close[1] && High[1] > Open[1] && Close[1] > Low[1]; if( sellcondition ) { open=Open[1]; high=High[1]; } if(Bid > open && Bid < high) { OrderSend(Symbol(),OP_SELL,0.01,BidPrice,3,0, 0,"",0,0,clrRed); }
