Subject: [amibroker] system tester & pastaga
> Tomacz,
> I am bugged with buyprice & sellprice on stop

> 1/for me a system with stop is :
> a buy = binary peak ( 0 or 1)
> a sell= binary peak ( 0 or 1)
> a buyprice= a price between the H and low when the buy ==1
> a sellprice= a price between the h and the low when the sell ==1
>
> 2/ so if I take
> Buy= N;
> Sell= Xb ;
> BuyPrice= C;
> SellPrice= C;
>
> the results are correct
>
> if I change to
> Buy= N;
> Sell= Xb ;
> BuyPrice= Np;
> SellPrice= Xp;
>
> where Np and Xp are the value of a stop, the results are wrong, even
> sometimes the buy&hold is wrong
>
> 3/youdon't believe me??

> try to plot the buyprice & sellprice , they gives correct value on a
