We will be sharing and discussing code at kobra.io. {TPStrat1} // Version 1.3 // TS EMA 12, 26 Inputs: TradeSize(1), // Number of options trade CutOffTime(CalcTime(Sessionendtime(0,1), -10)); // End of day (EOD) exit time Vars: double TradeSize(1), IntrabarPersist bool Filter(true), //used just before sending order IntrabarPersist double PriceBuyMarket(0); //order open price msg(""); //not used //Close Long Positions if XAverage(Close, 12) of Data2 < XAverage(Close, 26) of Data2 //Exponential Moving Average < Exponential Moving Average then begin Filter = (MarketPosition <> 0); if Filter then Sell ("LX") next bar at market; end; //Open Buy Order if XAverage(Close, 12) of Data2 > XAverage(Close, 26) of Data2 //Exponential Moving Average > Exponential Moving Average then begin Filter = true; if Filter then begin PriceBuyMarket = Close; Buy ("LE") TradeSize contracts next bar at market; end; end; // Sell at EOD else if = Time >= CutOffTime and MarketPosition(0) = 1 then Sell ("EOD") next bar at market; // sell if true
