Re: Different RSI in MetaStock ?

["Lionel Issen" <lissen@xxxxxxxxxxxxxx>]

Some of these differences are significant.  If you have checked this at
several internet sites and their calculations agree with yours, Then there
is a strong indication that Metastock is in errot.

Sometime back Guy Tann painstakingly checked several Metastock functions and
found them to be wrong. In part it was due to Metastock using only single
precision arithmetic, resulting in large roundoff errors, and to poor
internal algorithms.

Metastock needs to be redone from the ground up using state of the art
programming methods, not circa 1955 mainframe methods.

Subject: Different RSI in MetaStock ?


Hi all,

I wondered if others have noticed the same.
It seems that the calculation for RSI in MetaStock differs from the
standard RSI calculation.

I 'm trying to "translate" my MetaStock trading system into an Excel
sheet.
And because my MetaStock trading system contains RSI, I need
to "translate" the RSI calculation into Excel.

Attached Excel sheet contains my RSI calculation (sheet: calc 1).
Other calculations downloaded from the Internet give the same values
for RSI as my calculation (sheet: calc 2).

MetaStock RSI values are shown in red.

1. Which version is correct ?
2. How does MetaStock calculate their RSI ?

Thanks for your input.

Kind regards,
Onno
