[amibroker] Re: Identifying Elliott Waves using AFL

Group;

I am having a time trying to get this statement working:

       in= Sum(Ref(Buy,-1),120)==0 AND Ref(ina,-2) AND Sum(Out,3)==0;

It keeps returning true even when the component logicals are false.

The following code should create only one buy signal as
the second should not happen since there was already a but in the last
120 minutes.
But, two "buy" signals are created.
This can be demonsrated by pasting into the AA window and run on one 
stock...

Is this a Bug??  Any help would preserve my sanity...

            Thanks!
                     Walt

BTW: This is on a 1 minute chart...

//*************************************************

Buy=0;
Sell=0;

ina=(TimeNum()>94500 AND TimeNum()<100000)
OR
(TimeNum()>104500 AND TimeNum()<110000);

Out=TimeNum()>101500 AND TimeNum()<103000
OR
TimeNum()>111500 AND TimeNum()<113000;


in= Sum(Ref(Buy,-1),120)==0 AND Ref(ina,-2) AND Sum(Out,3)==0;
 
Buy=ExRem(in,Out);
Sell=ExRem(Out,in);

NumColumns=3;
Filter=Buy;

Column0=Buy;
Column0Name= "Buy";
Column1=Sum(Ref(Buy,-1),120)<1;
Column2= in ;
