[amibroker] Code giving great results

[nickrobn]

Have following code:


Buysig = buy conditions;
Sellsig = Sell conditions;

InTrade = Flip(Buysig,Sellsig);

Buy = Buysig  AND Ref(Intrade,-1)==0;
Sell = Sellsig AND Ref(Intrade,-1)==0;

I obtain much better results (higher profit, longer and fewer trades)
with the inclusion of Ref(Intrade,-1)==0 in the formula. Can anyone
tell me why?

Thanks,

Nick
