Hello,
The codes are correct.
You can get same buyprice and sell price
for two reasons
a) your system generates regular exit at bar that happens to have same price as entry bar
b) the NEXT bar after stop penetration bar happens to have same price as entry bar.
If you recollect what original poster asked for,
" want the stop function to check the PREVIOUS day Close instead of the H-L range."
So if current CLOSE price is X% lower than trade entry price (open) then trade
is exited NEXT bar. This is as per requirement of original poster.
Since the stop is executed at next bar, the price may be higher or lower than actual
stop target.
If it happens that next bar open gaps up to the price of entry bar you will see the same price.
If you can not program by yourself, there are 3rd party AFL coding services available either
at www.aflwriting.com or www.patternexplorer.com or support at amibroker.com can write
code for the fee http://www.amibroker.com/freesupport.html

Tomasz Janeczko
