What Is the Relative Strength Index?

Measures the speed and magnitude of recent price changes to evaluate overbought or oversold conditions. Ranges from 0 to 100. RSI compares the average gain to the average loss over a lookback period (default 14). When gains dominate, RSI rises toward 100. When losses dominate, it falls toward 0. Above 70 is traditionally overbought; below 30 is oversold.

RSI Signals on GBP/USD

Buy when RSI crosses above 30 from below (oversold recovery). Sell when RSI crosses below 70 from above (overbought rejection). Divergence between RSI and price is the strongest signal — price makes a new high but RSI doesn't = bearish divergence.

Outside peak hours, RSI signals are noisier because volume thins and spreads widen.

How to Trade GBP/USD with RSI

  1. 1

    Add RSI to your chart

    Open GBP/USD on your preferred timeframe (H1 or H4 or D1 recommended). Apply the Relative Strength Index with default settings: Period: 14. Overbought: 70. Oversold: 30.

  2. 2

    Confirm the trend on a higher timeframe

    Before acting on any RSI signal, check one timeframe up for the prevailing trend. Trade RSI signals in the direction of the higher-timeframe trend for higher win rates.

  3. 3

    Wait for a clear RSI signal

    Don't anticipate — wait for the signal to complete. Buy when RSI crosses above 30 from below (oversold recovery).

    Use the position size calculator. Risk 1% per trade. On GBP/USD with a 110-pip daily range, typical stops are 22–44 pips.

    Manage and journal

    Move stop to breakeven after 1R. Let the trade run toward 2–3R. Journal the RSI signal quality so you build data on which signals work best for GBP/USD.

When RSI Fails on GBP/USD

No indicator works in every condition. RSI is a momentum indicator, which means it performs best in range-to-trend transitions and struggles when momentum is flat. On GBP/USD, avoid using RSI during the Asian session (for this pair) and during the first 5 minutes of major news releases when price spikes are noise, not signals.
