Up until recently, Price Trend vs Market was described in the Help Files as:
30 Day Price Trend vs Market - [(Latest Close Price of Stock / Latest Close price of S&P 500 divided by [(Close Price 4 weeks ago / Close Price of S&P 500 4 weeks ago)]*100
5 Day Price Trend vs Market - [(Latest Close Price of Stock / Latest Close Price of S&P 500)] divided by [(Last Weeks Close Price / Last Weeks Close Price of S&P 500] *100
These have been changed. The procedure is now:
1) Calculate the Market Index as described in Help Files. This is a market value index as opposed to a price index and is calculated much like the SP-500 but on a different set of stocks.
2) The Relative Strength Indicator (RS) is calculated for each stock vs the Market Index, which is the stock's close divided by the Market Index value for each day.
3) The P Day Price Trend vs Market for a stock is given by:
100*LRSlope(RS,P)/AVG(RS,P)
where LRSlope is the Linear Regression Slope and AVG is the Simple Moving Average.
Help Topics does not say that the above is Price Trend vs Market but if you go through the description and know your arithmatic you will find that to be the case.
Thanks,
