Understanding RSI Formula and Calculation

The Relative Strength Index calculation is based on an accurate formula that is intended to calculate the rate of change and the direction of price fluctuations. The standard calculation is predicated on a 14-period time frame. The following is a step for calculating it:

Step 1: Calculate Average Gain and Average Loss

Average Gain = Sum of gains over the past 14 periods / 14

Average Loss = Sum of losses over the past 14 periods / 14

Step 2: Calculate the Relative Strength (RS)

RS = Average Gain / Average Loss

Step 3: Apply the RSI Formula

RSI = 100 – (100 / (1 + RS))

How to Read RSI Indicator

Reading the RSI involves understanding overbought and oversold conditions, which often align with price action patterns. A reading above 70 generally signals potential selling pressure, while below 30 may suggest a buying opportunity.

1. RSI Below 20: Extremely Oversold

• The market is significantly oversold, indicating strong negative pressure.
• Perhaps a reversal or bounce-back is on the horizon. Traders should be cautious of sudden spikes.

2. RSI Below 30: Oversold Zone

• Oversold indicates that sellers are in control of the asset price.
• Once a reversal signal is seen, this might be a good time to purchase.

3. RSI 30-50: Bearish Momentum

• Selling pressure on the asset is rising as it falls in price.
• This might be an excellent opportunity to short sell or wait for an indication that the trend will soon reverse.

4. RSI Above 60: Bullish Momentum

• The asset is showing strength, and bullish momentum is in charge.
• Traders need to consider chasing the upward trend, and watch for any weakening signals.

5. RSI Above 70: Overbought Zone

• Strong bullish momentum has caused the asset to be overbought.
• Traders can expect potential profit-booking or a minor correction soon.

6. RSI Above 80: Extremely Overbought

• The market is highly overbought, which may indicate that the trend is reaching its breaking point.
• Traders should pay attention to any reversals or consider locking in profits at this stage.

Tip: Extreme RSI values, such as below 30 or above 70, indicate strong bullish or bearish momentum. Traders should manage risk carefully and use tools like stop loss and take profit orders to maintain discipline.

How to Use RSI Divergence Indicator

Traders may improve their trading approach by learning to utilize RSI divergence indicators. These indicators will assist you in entering or exiting the market at the right times. The following are the steps to take in order to understand how to trade using the RSI divergence indicator.

Step 1: Identify the RSI Divergence Type

There are two types of RSI divergences:

RSI Bullish Divergence

This happens when the RSI makes lower lows than the price does. It might be a sign that selling pressure is falling, which could lead to an upward reversal.

RSI Bearish Divergence

This occurs when the price reaches greater highs while the RSI reaches lower highs. It suggests that the purchasing excitement is decreasing, which might result in a downward trend.

Step 2: Set Up the Indicator on the Chart

You have to open your trading platform and add the RSI indicator from the technical analysis tools. Use the default settings (usually 14-period) unless you have a preferred customized value.

Step 3: Look for Divergence Near Key Support or Resistance Levels

RSI divergence is more powerful when it occurs at significant support (for bullish divergence) or resistance (for bearish divergence) levels.

Step 4: Check for Overbought or Oversold Conditions

Divergence signals near the overbought (RSI above 70) or oversold (RSI below 30) zones tend to be more reliable, especially when signaling potential reversals.

Step 5: Confirm With Other Indicators

RSI divergence should be confirmed by other indicators or patterns like trendlines, moving averages, or candlestick patterns to increase the reliability of the signal.

Step 6: Time Your Trade Entry and Exit

You can enter a trade when the RSI divergence aligns with a reversal pattern. Additionally, traders should set stop-loss and take-profit levels to mitigate the risk.

RSI Divergence Indicator Settings for Intraday Trading

A 14-day period is the default setting for the Relative Strength Index since it is the norm across most trading platforms. On the other hand, this level is often adjusted to lower periods, typically between 9 and 11, by day traders and other short-term intraday traders. This setting is excellent for capturing shorter-term price fluctuations and market movements.

For intraday trading strategies, many traders prefer shorter RSI periods, such as 9 or 11, to capture quick price swings. The right setting depends on your preferred timeframe and risk management approach.

No single indicator, including RSI, guarantees accurate intraday signals. Market volatility, strong trends, or range-bound conditions can all reduce reliability. Traders should treat RSI as one tool among many and confirm decisions with broader technical and market context.
