Description:
Moving Average & Price Crossover

 

Formula Parameters:
Length : 40

 

Notes:
This is the almost simpliest strategy a trader can imagine. It is
based on moving average concept. A Moving Average is an indicator
that shows the average value of a security's price over a period of
time. When calculating a moving average, a mathematical analysis of
the security's average value over a predetermined time period is made.
As the security's price changes, its average price moves up or down.
