Hello,
yes, I know there isn't in AFL a function
equivalent to PREV. I tried to use a VB Script, but I'm not able enough. Do
you know if there is, somewhere on the WEB, the original Guppy's
formula?
Best regards,
Franco

hello,there is not prev function in
Amibrokerprev is a recursive function, BUT you can defind it
with a scripting languagemy choise was since one year was C++but there
is jscript and vbscriptabout the cbl, I think the ms version is not
matching the guppy principles but only an adaptation .this is notthe
best trailing stop...steph> > 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> >

same question again, but I'd need to know if it's possible to convertfrom
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 possibleto
translate the following formula to AFL? LowDays := Input("Enter # days to
cover last LOW for CBL calc'n:", 3, 55, 13);

PREV, {previous CBLlo, else...} If(Ref(H,-2) > Ref(H,-1) AND Ref(H,-2)

Ref(H,-3) > H) AND (Ref(H,-2)> H OR Ref(H,-1) > H), {then ... }
Ref(H,-3), {3rd day back high,else...} If((Ref(H,-4)> Ref(H,-3) AND
Ref(H,-4) > Ref(H,-2) AND Ref(H,-4) > Ref(H,-1) AND Ref(H,-4) >
