- RSI Line
RSI is based on the ratio of the amount of the upward price changes to the amount of the downward changes over 14 days. This period was used by the oscillator’s creator, and we recommend using it.
If you increase the RSI period, the oscillator will give fewer signals, but they will be more accurate.
The RSI line can move between 0 and 100. In doing so, it crosses 30 and 70. The zone below 30 is the oversold zone and above 70 is the overbought zone.
