What Is the RSI Indicator and How Does It Work in Trading?

The Relative Strength Index (RSI) is one of the most widely used technical indicators in trading. It helps traders identify whether a market is overbought or oversold, signaling potential price reversals or continuation setups.

Whether you trade manually on MT4, MT5, or through a prop firm like FundedNext, understanding how the RSI works can dramatically improve your decision-making and timing.

What is the RSI Indicator?

The RSI (Relative Strength Index) is a momentum oscillator developed by J. Welles Wilder Jr. in 1978. It measures the speed and magnitude of price changes to identify market momentum and potential reversal zones.

• Scale: RSI ranges from 0 to 100
• Purpose: It quantifies market strength, showing whether bullish or bearish momentum is increasing or weakening.
• Interpretation:
  • Above 70: Overbought (potential downward correction)
  • Below 30: Oversold (potential upward correction)

RSI is a favorite among CFDs and prop traders because it adapts easily across timeframes and instruments, whether you’re trading indices, gold (XAUUSD), or currency pairs on your FundedNext account.

How the RSI Indicator Is Calculated

The RSI formula uses average gains and losses over a set period, most commonly 14 candles:

RSI = 100 – [100 / (1 + RS)],

where RS (Relative Strength) = Average Gain / Average Loss

Average Gain: The average amount of price gains over the chosen period.

Average Loss: The average amount of price losses over the chosen period.

Example:

If the average gain is 1.5% and the average loss is 0.5%, then:

RS = 1.5 / 0.5 = 3

→ RSI = 100 – [100 / (1 + 3)] = 75

An RSI of 75 indicates the asset may be overbought, suggesting traders might prepare for a pullback or short opportunity.

How RSI Works in Trading

In simple terms, RSI helps you read momentum shifts so you can time entries, exits, and confirmations with more clarity.

1. Identifying Overbought and Oversold Conditions

When RSI exceeds 70, it suggests an overbought market. When it dips below 30, it signals oversold conditions.

These thresholds help traders anticipate potential reversals and plan entries or exits accordingly.

Example:

If XAUUSD’s RSI hits 75 after a sharp rally, traders may expect a short-term pullback before price resumes trending.

2. Spotting Divergences

A divergence occurs when price and RSI move in opposite directions, often a sign of an upcoming reversal.

• Bullish Divergence: Price makes lower lows while RSI makes higher lows, indicating a possible bullish reversal.
• Bearish Divergence: Price makes higher highs while RSI makes lower highs, signaling a potential bearish reversal.

These signals become even more reliable when combined with support/resistance or candlestick confirmations.

3. Confirming Trend Strength

RSI doesn’t just highlight reversals; it also helps confirm trend strength:

• In uptrends, RSI often oscillates between 40 and 90.
• In downtrends, it typically stays between 10 and 60.

For FundedNext traders, RSI can be used alongside other tools to maintain consistency throughout both the Challenge Phase and Funded Account, ensuring disciplined decision-making within daily and overall loss limits.

RSI Trading Strategies You Can Use at FundedNext

These RSI strategies can help you build clearer entry rules and stay consistent across different market conditions.

RSI Reversal Strategy

Ideal for range-bound conditions.

Steps:

1. Wait for RSI to move above 70 (overbought zone) or below 30 (oversold zone).
2. Confirm using price action or chart structure.
3. Enter countertrend trades with defined stop-loss levels.

You can freely apply this strategy in your FundedNext CFDs account, RSI is an approved indicator with no restrictions.

RSI Trend-Following Strategy

Perfect for traders who prefer to follow the market’s dominant direction.

Steps:

1. Identify the trend using a moving average.
2. In an uptrend, look for RSI to pull back toward the 40 zone before taking long entries. In a downtrend, watch for RSI pullbacks toward the 60 zone as potential short opportunities. This helps you enter in alignment with the prevailing trend rather than against it.
3. Confirm with structure breaks or higher timeframe analysis.

FundedNext’s Stellar models allow these setups across MT4, MT5, Match-Trader, and cTrader, letting traders customize RSI parameters for their preferred timeframes.

RSI Divergence Strategy

Best for anticipating turning points.

Setup Example:

1. RSI shows lower highs while price makes new highs, indicating a bearish divergence.
2. Confirm with a trendline break or candlestick reversal before entry.

RSI divergence setups are especially useful for prop traders managing consistency goals, as they help avoid impulsive trades and preserve drawdown limits.

Best RSI Settings and Timeframes

While the default 14-period RSI works for most situations, FundedNext traders can customize parameters to match their strategies:

• 7–9 Period RSI: More sensitive, ideal for scalpers and day traders.
