[amibroker] Re: AFL looping question!

["tayamaan" <tayamaan@xxxxxxxxx>]

Hi Ed, the loop is just a simple profit target stop for testing other 
parts of my systems and a reference to the Entry Price.

Once changing the "Close[ i ] > priceatbuy * 1.2"  expression and 
basically making it a stop, things go wrong. Or is it my logic? LOL 

Am not too familiar with looping and try to understand why this 
doesn't work.

Thanks

priceatbuy in the loop also needs to be handled as an element, like 
priceatbuy[ i ],  but then still I can't figure out what you are 
trying to do,
