Key Takeaways
- RSI measures the speed and change of price movements.
- Above 70 is considered 'overbought' (potential sell signal).
- Below 30 is considered 'oversold' (potential buy signal).
- RSI is a tool, not a crystal ball. Always use it with other confirmations.
The Relative Strength Index (RSI) is one of the most popular and versatile indicators available to traders. But what does it actually do, and how can you use it to find better trading opportunities? This guide will break it down for you.
What is the RSI?
Developed by J. Welles Wilder, the RSI is a momentum oscillator that measures the speed and change of price movements. It oscillates between 0 and 100 and is typically displayed as a line graph below your main price chart. Its primary purpose is to identify "overbought" and "oversold" conditions in a market.
The Core Concept: Overbought vs. Oversold
This is the most common way to use the RSI. The indicator has two key levels:
Overbought (70) : When the RSI moves above 70, it suggests that an asset may be overvalued and is a good candidate for a price pullback or reversal. This is often seen as a potential sell signal.
Oversold (30) : When the RSI moves below 30, it suggests that an asset may be undervalued and is poised for a bounce. This is often seen as a potential buy signal.
It's simple, but powerful. However, it's crucial to remember that an asset can remain overbought or oversold for extended periods in a strong trend. Never trade on an RSI signal alone!
A Simple RSI Strategy
Here’s a basic framework for using RSI signals:
1. Identify the primary trend. Is the market generally moving up or down? It's often best to only take signals that align with the trend (e.g., only look for oversold/buy signals in an uptrend).
2. Wait for an RSI signal. Watch for the RSI to cross below 30 (oversold) for a potential buy, or above 70 (overbought) for a potential sell.
3. Look for confirmation. Don't enter the trade immediately! Wait for price action to confirm the signal. This could be a bullish candlestick pattern (like a Hammer or Engulfing candle) at a support level after an oversold signal.
4. Set your risk. Always use a stop-loss. A logical place is just below the recent low for a buy signal, or just above the recent high for a sell signal.
Putting It All Together
Analyzing charts for these patterns takes practice. You can use our AI Chart Analyzer to help you spot potential support/resistance levels and candlestick patterns that can confirm your RSI signals. Once you have a trade idea, use the **Risk/Reward Calculator** to ensure the trade is worthwhile before you enter.
