Not exactly, Your formula gives 1 if Buy and 0 if sell Then it gives 0 at the begin of the array (where we are not Buy nor Sell) and we may believe that we are Sell.
The complete formula give 0 at the begining (where Not buy and not sell) and after she gives 1 When Buy and -1 when Sell. ----- Original Message ----- From: Ron Rowland To: [email protected] Sent: Friday, March 23, 2007 3:29 PM Subject: [amibroker] Re: In Trade Index I believe the following accomplishes the same. inTrade = Flip(Buy,Sell) ; --- In [email protected], Graham <[EMAIL PROTECTED]> wrote: > > Sorry made mistake > > inTrade = iif(Flip(Buy,Sell),1,-1) ; > > -- > Cheers > Graham > AB-Write >< Professional AFL Writing Service > Yes, I write AFL code to your requirements > http://www.aflwriting.com > > > > On 23/03/07, Graham <[EMAIL PROTECTED]> wrote: > > I think you will find this an easier solution > > > > inTrade = Flip(Buy,Sell) - 1; > > > > > > -- > > Cheers > > Graham > > AB-Write >< Professional AFL Writing Service > > Yes, I write AFL code to your requirements > > http://www.aflwriting.com > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > ----- Original Message ----- > > > From: Alain Baur > > > To: [email protected] > > > Sent: Thursday, March 22, 2007 3:48 AM > > > 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 > > > > > > > > > > > > > > > > > > ________________________________ > > > > > > > > > > > > >
