Hi, error is bool dn = OpenValue > PrevHighValue; and next !dn[sc.Index - 1] you can't turn a bool variable into an array, variable is only one value I hope I understand what you need...I choose the fastest and easiest way 1) create new SGs SCSubgraphRef up = sc.Subgraph[3]; SCSubgraphRef dn = sc.Subgraph[4]; 2) change rows up and dn up[sc.Index] = OpenValue < PrevLowValue ? 1.0f : 0; dn[sc.Index] = OpenValue > PrevHighValue ? 1.0f : 0; 3) correct condition if ((up[sc.Index] == 1.0f)&&(dn[sc.Index-1] == 0)) { BuyEntrySubgraph[sc.Index] = sc.Low[sc.Index]; } // also change second condition for SELL I'm not at the computer with c ++ right now, I'm writing it out of my head, but it should work. Perhaps it helped you. Date Time Of Last Edit: 2019-09-02 11:58:10
