Hi, Try something like the following. The Buy/Sell seems to work. You can add the Short/Cover using the same principles. The code assumes that you are trading at the Close on the day of the signal. SetTradeDelays(0, 0, 0, 0); BuyPrice = Close; SellPrice = Close;
previousClose = Ref(Close, -1); rsi2 = RSI(2); Sell = Cross(rsi2, 70); bull100 = Close > EMA(Close, 200) AND Sum(rsi2 < 25, 2) == 2; inFirstPos = Flip(bull100, Sell); bull200 = Close < previousClose AND inFirstPos AND Ref(inFirstPos, -1); inSecondPos = Flip(bull200, Sell); bull300 = Close < previousClose AND inSecondPos AND Ref(inSecondPos, -1); inThirdPos = Flip(bull300, Sell); bull400 = Close < previousClose AND inThirdPos AND Ref(inThirdPos, -1); inFourthPos = Flip(bull400, Sell); firstTrigger = ExRem(inFirstPos, Sell); secondTrigger = ExRem(inSecondPos, Sell); thirdTrigger = ExRem(inThirdPos, Sell); fourthTrigger = ExRem(inFourthPos, Sell); Buy = firstTrigger + (secondTrigger * sigScaleIn) + (thirdTrigger * sigScaleIn) + (fourthTrigger * sigScaleIn); SetPositionSize(IIf(firstTrigger, 100, IIf(secondTrigger, 200, IIf(thirdTrigger, 300, 400))), spsShares); priceColors = IIf(Close > previousClose, colorDarkGreen, IIf(Close < previousClose, colorDarkRed, colorDarkGrey)); buyColors = IIf(firstTrigger, colorGreen, IIf(secondTrigger, colorLime, IIf(thirdTrigger, colorYellow, colorOrange))); Plot(Close, "Price", priceColors, styleBar); PlotShapes((Buy > 0) * shapeUpArrow, buyColors, 0, L, -10); PlotShapes(Sell * shapeDownArrow, colorRed); Mike --- In [email protected], "cvanhaesendonck" <carl....@...> wrote: > > I posted some days ago but got no answer; however this system is powerfull yet simple: it scales in after the initial signal then exit quickly as soon as RSI(2) oberbought. > Problem I struggle with the code below: I can see the multiple buy entry arrows on the chart but backtest will only take the initial signals. > Please help with this - in return you will discover a very interesting system.
