Re: [amibroker] In Trade Index

["wavemechanic" <fimdot@xxxxxxxxx>]

You have to take care of the conditions before the first buy/sell signal.  So try something like this which will result in intrade == 0 before the first signal and then your 1, -1 thereafter:

 

buybar = iif(barindex() == 0, 0, valuewhen(buy, barindex(), 1));

sellbar = iif(barindex() == 0, 0, valuewhen(sell, barindex, 1));

intrade = iif(barbuy > barsell, 1, iif(barsell > barbuy, -1, 0)):

Subject: [amibroker] In Trade Index

Hi

I would like to create an index ( "InTrade") which indicates if i am On the market or no.

 

This formula works well but only after the two first trades (Buy then sell or sell then Buy)

 

SetChartOptions(1,chartShowDates);

GraphXSpace = 10 ;

Plot(Close, "C", colorBlack, styleCandle);

X = BarIndex();

MA10 = MA(C, 10) ;

MA50 = MA(C, 50);

Plot(MA10, "MA10", colorBlue, styleLine);

Plot(MA50, "MA50", colorRed, styleLine);

Buy = Cross(MA10, MA50);

Sell = Cross(MA50, MA10);

BarBuy = ValueWhen(Buy, X, 1);

BarSell = ValueWhen(Sell, X, 1);

PlotShapes(IIf(Buy, shapeUpArrow, shapeNone), colorGreen, 0, L, -12);

PlotShapes(IIf(Sell, shapeDownArrow, shapeNone), colorRed, 0, H, -12);

intrade = IIf( BarBuy > BarSell , 1, -1);

Title = " " + Name() + " - " + Date() + " - BarBuy = " + BarBuy + " - BarSell = " + BarSell

+ " - Intrade = " + intrade + " " ;

 Is it possible to write an other formula which works since the beginning of the Array ? 

 

 

Thank's for your response
