Re: [amibroker] MS PREV

[Bernard Bourée <bbouree@xxxx>]

Hi Tomasz and Steve,
 
Thank you for your reply.
Here is my formula:
 
aa= C - Ref(C,4);
bb=Sum(Abs(Roc(C,1,$)),4)
cc=(Abs((AA)/BB))
dd=((2/3)-(2/31))+(2/31)
ee=(CC*DD)^2
ff=(C-Ref(C,-1))
Sig:=If(Cum(1)=5, Ref(C,-1)+EE*FF, PREV + EE * (C - 
PREV))
 
Regards

Hi,
 
Steve pointed you correctly to JScript/VBScript 
but in fact some formulas
do not really need PREV. People tend touse it 
much more often than it is really needed.
Send me the formula and I will tell you 
how to convert it into AFL in an efficient 
way.
 
Please note that PREV in fact is VERY slow and 
still does imply lots of limitations to coding formulas.
With JScript/VBScript you are completely free - 
there are virtually no limits in the language.

At present you have to do this inside a VBScript or 
JScript area by looping through an array that has been inialized.I 
have used this in a couple of demo scripts and indicators which has been 
put up on the board.SteveAt 02:20 PM 6/9/01 +0000, you
