These filters compare the price of the last print for a stock to that of the 8 period simple moving average.  These SMA’s are determined on 2, 5, 15, 60 minute time-frames.

A positive number means that the current price is above the moving average.  A negative number means the current price is below the moving average.

The values entered for these filters are percentage (%).  The formula is (Percent Change) = ((Last Price) - (SMA)) / (SMA) * 100.

The distance from the 8 period SMA is often used to determine the size of a short term trend when it starts.
