The RSI indicator is a trading tool that help you identify high-probability trend reversal setups.
But you need to use the right RSI indicator settings as shown in the video (default settings are too slow).
Here's how to read the RSI indicator.
Oversold area (0-30) - Too many sellers in the market.
Neutral area (30-70) - Neutral area.
Overbought area (70-100) - Too many buyers in the market.
