So it basically has 3 lines, and i want for long trades that closed bar price has crossed middle line up, but not upper line. i Cannot get it work in my if statement. At the moment i do get middle line cross up, but it also shows buy signal if candle crosses upper line which is not good. Please help... my EA code: // the input variables of the EA input ENUM_TIMEFRAMES TimeFrame = PERIOD_CURRENT; input int AMAPeriod = 10; input ENUM_APPLIED_PRICE AMAPrice = PRICE_CLOSE; input int Nfast = 2; input int Nslow = 30; input double GCoeff = 2; input int PriceFilter = 5; input maTypes PriceFilterMode = ma_smoo; input bool Interpolate = true; //+------------------------------------------------------------------+ //| Expert initialization function | //+------------------------------------------------------------------+ int OnInit() { //--- //--- return(INIT_SUCCEEDED); } //+------------------------------------------------------------------+ //| Expert deinitialization function | //+------------------------------------------------------------------+ void OnDeinit(const int reason) { //--- } //+------------------------------------------------------------------+ //| Expert tick function | //+------------------------------------------------------------------+ void OnTick() { //--- double band_middle = iCustom(_Symbol,_Period,"kaufman_ama_averages_filtered_ATR bands",TimeFrame, AMAPeriod, AMAPrice,Nfast, Nslow, GCoeff, PriceFilter, PriceFilterMode,Interpolate, 0,0 ); double band_1 = iCustom(_Symbol,_Period,"kaufman_ama_averages_filtered_ATR bands",TimeFrame, AMAPeriod, AMAPrice,Nfast, Nslow, GCoeff, PriceFilter,PriceFilterMode,Interpolate, 1,0 ); double band_2 = iCustom(_Symbol,_Period,"kaufman_ama_averages_filtered_ATR bands",TimeFrame, AMAPeriod, AMAPrice,Nfast, Nslow, GCoeff, PriceFilter,PriceFilterMode,Interpolate, 2,0 ); double band_3 = iCustom(_Symbol,_Period,"kaufman_ama_averages_filtered_ATR bands",TimeFrame, AMAPeriod, AMAPrice,Nfast, Nslow, GCoeff, PriceFilter,PriceFilterMode, Interpolate, 3,0 ); double band_up = iCustom(_Symbol,_Period,"kaufman_ama_averages_filtered_ATR bands",TimeFrame, AMAPeriod, AMAPrice,Nfast, Nslow, GCoeff, PriceFilter,PriceFilterMode, Interpolate, 4,0 ); double band_down = iCustom(_Symbol,_Period,"kaufman_ama_averages_filtered_ATR bands",TimeFrame, AMAPeriod, AMAPrice,Nfast, Nslow, GCoeff, PriceFilter,PriceFilterMode, Interpolate, 5,0 ); //strategy double band_middle_curr = iCustom(_Symbol,_Period,"kaufman_ama_averages_filtered_ATR bands",TimeFrame, AMAPeriod, AMAPrice,Nfast, Nslow, GCoeff, PriceFilter, PriceFilterMode,Interpolate, 0,0 ); double band_middle_prev = iCustom(_Symbol,_Period,"kaufman_ama_averages_filtered_ATR bands",TimeFrame, AMAPeriod, AMAPrice,Nfast, Nslow, GCoeff, PriceFilter, PriceFilterMode,Interpolate, 0,1 ); double band_up_prev = iCustom(_Symbol,_Period,"kaufman_ama_averages_filtered_ATR bands",TimeFrame, AMAPeriod, AMAPrice,Nfast, Nslow, GCoeff, PriceFilter,PriceFilterMode, Interpolate, 4,1 ); double band_up_curr = iCustom(_Symbol,_Period,"kaufman_ama_averages_filtered_ATR bands",TimeFrame, AMAPeriod, AMAPrice,Nfast, Nslow, GCoeff, PriceFilter,PriceFilterMode, Interpolate, 4,0 ); Comment(band_up_prev); if(Close[0] > band_middle_curr && Close[0] < band_up_curr) { Print("open a buy order"); } } //+------------------------------------------------------------------+
