These filters compare the price of the last print for a stock to that of the 20 period simple moving average. These SMA’s are determined on 2, 5, 15 and 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 above the 20 period SMA is often used to determine the potential for longer trends.
