Re: [amibroker] countback line

["Franco Fornari" <ffpsi@xxxx>]

Grant,
 
thanks for your reply. Maybe you are referring to 
the dll shared by Stephan. I know it, but its logic seems rather different 
and I'd like to match it against Metastock's CBL.
 
Thanks again and best regards
 
Franco

Franco,     CBL has been converted somewhere 
here before but I can't find it at the moment, maybe if you check AB 
website formular page. I have a feeling it was also in one of Steven's 
DLL's. Sorry I'm not much help to you but at least you know it's here 
somewhere, I'll keep looking.

Hello Tomasz and 
All, sorry if I propose 
the same question again, but I'd need to know if it's possible to convert 
from Metastock language to AFL any formula containing PREV function. Tomasz 
showed many times, in past, how work AMA and AMA2 but, if I'm not wrong, 
this case seems different, because in "Countback line" Metastock formula, 
PREV doesn't refer to any averages but to hard values. Is it possible to 
translate the following formula to AFL? LowDays := 
Input("Enter # days to cover last LOW for CBL calc'n:", 3, 55, 13); 
If(LOW > LLV(LOW, LowDays), {then ...} PREV, {previous CBLlo, else...}
