Random Walk Index functions

["John R" <jrdrp@xxxx>]

Tomasz,

When converting some of my systems from Metastock I noticed that the
Amibroker RWI functions RWIHI and RWILO can return negative values whereas
the Metastock equivalents never fall below 0.

Is there a problem here or is it down to different interpretations of the
Michael Poulos work? Could you let me know the formula AB uses for these
functions.

Thanks
John
