Introduction:
The 'sma' indicator is used in indicator formula construction to
narrow the stock pre-screener results to include only those stocks
that have a simple moving average stock price restricted to the
parameters set for the sma indicator.
Calculation:
Add up each of the last x-day closing stock prices then divide the sum
by x.
Example:
Below is a chart of Intel (INTC) highlighting days where the 20-day
simple moving average stock price was greater than the 50-day simple
moving average.
