Folks,

Say i have buy = condition1;
Alert gets generated...Now few bars later again condition1 matches and another 
alert gets generated.
So i'd like add a filter that says Buy=condition1 and this is the first Buy in 
the past six bars so that buy signals don't repeat every other bar if the 
condition matches.

I tried something like this

 buy=condition1 and ref(buy,-1)=0 and and ref(buy,-2)=0 and and ref(buy,-3)=0 
and and ref(buy,-4)=0. 

But its not working.

How do I code this in AB 4.9?. Thanks.

cheers,Padhu
