Code:

RP = ( stock_close / index_close ) * 100

And then a 52 week moving average is added to the indicator to show the zero line.

So the longer version is:

Standard Relative Performance = (today's close of the stock divided by today's close of the index) * 100


Mansfield Relative Performance indicator

The formula of this indicator is a bit more difficult than the regular Standard Relative Performance indicator:

Code:

MRP = (( RP(today) / sma(RP(today), n)) - 1 ) * 100

Where:
RP = Standard Relative Performance indicator (see above)
SMA = Simple moving average over n days.
n = 52 for weekly charts, and n = 200 on daily charts

So to make it a bit clearer:

Mansfield Relative Performance = (( Today's Standard Relative Performance divided by Today's Standard Relative Performance 52 Week Moving Average )) - 1) * 100

I hope the above calculations all make sense, but if you need further assistance then chartmill.com did a good article on it which you can find here: http://www.chartmill.com/documentation.p...20Strength

Does anyone know how to set this up in Thinkorswim (TOS)?
