RE: [EquisMetaStock Group] ADX formula

["Andrew Tomlinson" <andrew_tomlinson@xxxxxxxxxxx>]

Actually, Welles Wilder did calculate the ADX in integer steps. Of course,
he was using hand calculations, so it made life easier. It's also why you
see 'Wilder's smoothing' in many of his indicators - much easier to
calculate on a hand-written spreadsheet than regular averages.

Try Directional Movement +DI and Directional Movement -DI for +DMI and -DMI.
I think that's what you're looking for. At least that's for the drop-down
indicators. For formulas you should use PDI() and MDI().

What's the problem with the ADX formula you're using? The canned ADX in
MetaStock is rounded to give only an integer output - probably not what the
author intended. The MetaStock code written by Equis and published in the
Oct99 TASC does not use rounding on the + or - DMI components, or the
output. Adding Round() to the "DIPlus" and "DIMinus" variables of that
formula makes those variables compatible with the canned + and - DI
Directional Movement indicators and PDI() and MDI() functions. Getting the
formula ADX output to agree with Directional Movement ADX has so far eluded
me.
