Hi Chorlton
There are two Forum DLLs in this group's files section. Check out http://finance.groups.yahoo.com/group/equismetastock/files/Equis%20Forum%20DLL/
The current Forum Dll is also available as Forum20.dll from the Files section at http://forum.equis.com/ .I suggest you change the name of the DLL to keep to Forum.DLL, purely to save space when calling it. That's not necessary but it can help prevent excessively long ExtFml() calls. What will be necessary if you use the newer 188KB DLL is changing the syntax from VarMov to Mov. VarMov was used in 1 or more earlier versions, no doubt including the one used by Preston's formula. The GH variable would be written like this if you renamed the DLL from Forum20.DLL to Forum.DLL.
GH:=ExtFml( "Forum.MOV", HIGH, ATR(pdatr)*factor,e);
It would be written like this if you retained the Forum20.DLL name when downloading.
GH:=ExtFml( "Forum20.MOV", HIGH, ATR(pdatr)*factor,e);
Obviously the two DLLs cannot reside in the same "External Function DLLs" folder with the same name, but each will work whatever name you give them as long as you change your ExtFml() code syntax to suit. As long as each version has a unique name they can both reside in the same folder.
The larger file is the one with the least issues but that's not to say that all issues have been resolved. There were severe speed problems with the exponential MA function in at least one of the older versions. That problem was resolved with the 188KB file.
Regards
Roy

Subject: [EquisMetaStock Group] Re: Help with coding an indicator...Gann HiLo ATR
Hi Preston,
When I run this code, I get the following error message : This DLL
does not exist in the MSX DLL folder.
I'm assuming that this is because its trying to call the
ExtFml "ForumDLL.VarMOV"? Where can I get this from and how do I
incorporate it to make this code work?
Thanks in advance,
Chorlton
