[amibroker] In Trade Index

[Alain Baur]

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 ?
