How we make money
The RSI can provide useful insights in non-trending or sideways market conditions. It can identify potential overbought and oversold conditions, which might indicate forthcoming price swings even in a range-bound market. Some traders consider it a buy signal if a security’s RSI reading moves below 30. This is based on the idea that the security has been oversold and is therefore poised for a rebound.

- Wilder considered RSI overbought above 70 and oversold below 30.
- Similarly, an overbought reading during a downtrend is much lower than 70.

Shares with more, or stronger, positive changes have a higher RSI value than those with more or stronger negative changes.

Since the indicator displays momentum, it can stay overbought or oversold for a long time when an instrument has significant momentum in either direction. In addition, it does not predict how big or small the following price move will be. Day trading involves buying or selling assets within the same trading day.
