RSI Alert Signal is a price following oscillator that generates trading signals based on its parameters, which values vary between 80 and 20. Below 20 indicates an oversold state, and values above 80 indicate an overbought state. The alert will notify if the oscillator line goes out of the overbought or oversold zone. It is a signal for opening a long position. If it goes out the oversold zone it is a signal for opening a short position.
