The Moving Averages alert is a technical instrument used to determine a stock's movement at support and resistance levels. You can set thresholds for parameters like SMA and EMA here. In the example below, thresholds have been set at 20. 

You can also set the frequency of alerts to 15 minutes, 30 minutes, 1 hour, or a day. You will receive alerts on your registered email ID when the stocks in your list cross the moving average thresholds.
