The Relative Strength Index (RSI) is a momentum oscillator that measures the speed and magnitude of price movements. Developed by J. Welles Wilder Jr., it oscillates between 0 and 100, providing traders with overbought and oversold signals.

TradingView setup and RSI mastery
To add RSI to your TradingView chart, click the "Indicators" button at the top of the chart, search for "Relative Strength Index", and select it. The default 14-period setting is recommended for beginners. You can customize the overbought (70) and oversold (30) levels in the indicator settings.
Day traders often use shorter RSI periods (9-11) for more responsive signals. Common setups include RSI(9) with 80/20 levels for volatile markets, or RSI(14) with 70/30 levels for more reliable signals. Test different settings with your specific trading style and market conditions.
While RSI is powerful, professional traders combine it with other indicators and price action analysis. Use RSI for momentum confirmation alongside support/resistance levels, moving averages, and volume analysis. This multi-indicator approach reduces false signals and improves accuracy.
Bullish divergence occurs when price makes lower lows but RSI makes higher lows. Bearish divergence is when price makes higher highs but RSI makes lower highs. Use TradingView's drawing tools to connect the peaks/troughs on both price and RSI to spot these powerful reversal signals.
RSI works on all timeframes but signals are more reliable on higher timeframes (4H, Daily). Scalpers use 1-5 minute charts, day traders prefer 5-15 minute charts, and swing traders focus on 1H-Daily charts. Always confirm signals across multiple timeframes for better accuracy.
Click the gear icon next to RSI in your indicators list, then select "Style". Here you can change line colors, thickness, and background fills. Many traders use green for the RSI line, red fills for overbought zones (>70), and blue fills for oversold zones (<30) for better visual clarity.
