G/M Bruce,

There has been discussion on another forum about Cutler's RSI.  I searched the Discussion Groups here but did not get a hit on it.  The Information is from wikipedia.  Could you see if a TC2000 PCF is possible.  Thanks

Cutler's RSI

A variation called Cutler's RSI is based on a simple moving average of U and D,^[4] instead of the exponential average above. Cutler had found that since Wilder used an exponential moving average to calculate RSI, the value of Wilder's RSI depended upon where in the data file his calculations started. Cutler termed this Data Length Dependency. Cutler's RSI is not data length dependent, and returns consistent results regardless of the length of, or the starting point within a data file.

Cutler's RSI generally comes out slightly different from the normal Wilder RSI, but the two are similar, since SMA and EMA are also similar.

Just use the plain RSI indicator instead of the RSI - Wilder's indicator.

Since the RSI built into the Personal Criteria Formula Language is the plain RSI and not the Wilder's smoothed version, something like a 14-Period Cutler's RSI could be written simply as:

RSI14

RSI and Wilder's RSI

Thank you Bruce.

Have a good weekend

You're welcome.
