Re: [amibroker] what am I doing wrong??

hi,

 

thanks for your reply.

 

That doesn't seem to solve it.  I now used 100000 instead of 10000

 

Using my data for CEPH (Nasdaq Cephalon) the last buy I get is on 12/21/2004 (in the chart). The explore shows the last buy on 12/13/2004 and gives a 0 on 12/21/2004. This example is maybe looks strange. My real problem I sent yesterday to the helpdesk but to illustrate the problem I used this smaller example.

 

The general problem I see is that I fill my Buy and Short arrays and use them to build my chart. All seems good up to this point. Then I do a backtest or an explore and I see something different. I get signals on different dates or no signals at all.  Hope I am not overlooking something really stupid ....

 

rgds, Ed

Hello,

 

If your data set has more than 10000 quotes you have to enlarge the

number of bars you specified in SetBarsRequired.

hi,

 

can't figure out what I am doing wrong. Below a simple example. I create an array using a function. This array I use to find Buy signals. I put the buy signals in a chart. All seems good. Then I do an explore and then I see that the explore puts the buy signals at a different date. There seems nothing strange about the code. What could be wrong?

 

Ed

 

 

function ffZig(vv,pp) {

   // initialize fzg array
   fzg = 0;

   // perform loop to fill fzg array
   for( i = 0; i < BarCount; i= i + 10 ) {

      fzg[ i ] = 1;
   }
   
   return fzg;
}


SetBarsRequired(10000,10000);
ZZ = ffZig(C,0) ;

Buy = ZZ == 1;
Short = 0;

PlotShapes( shapeUpArrow*Buy, colorGreen);
Plot(C, " ", colorBlue,  styleCandle ) ;

Filter = 1;
AddColumn(Buy,"Buy");
