How To Calculate RSI In Excel

Introduction

Understanding the Relative Strength Index (RSI) is crucial for traders analyzing market momentum. Calculating RSI in Excel involves a series of steps, including data organization and formula application.

This guide walks through the traditional Excel process, but you'll discover how Sourcetable's AI-powered spreadsheet platform lets you calculate RSI and perform any analysis simply by chatting with an AI assistant. Sign up for Sourcetable to analyze your data through natural conversation instead of complex formulas.

Calculate RSI in Excel

To calculate the Relative Strength Index (RSI) in Excel, follow a systematic process to determine the average gains and losses over a 14-day period. The RSI formula, RSI = 100 – 100 / (1 + RS), where RS is the Relative Strength, forms the core of the calculation.

Step 1: Calculate Daily Price Changes

Start by listing the daily closing prices. Then, compute the daily price changes. Subtract the previous day's price from the current day's price to find the gain or loss for each day.

Step 2: Separate Gains and Losses

Separate the gains from the losses. Record positive values for gains and use zero for days with losses. Conversely, record the absolute value of losses and use zero for days with gains.

Step 3: Compute Averages

Calculate the average of the up moves and down moves over the last 14 days. Sum the gains and divide by 14 for the average gain. Similarly, sum the losses and divide by 14 for the average loss.

Step 4: Calculate Relative Strength (RS)

Divide the average gain by the average loss to get the RS value. This represents the momentum of the price movements.

Step 5: Compute RSI

Apply the RSI formula: RSI = 100 – 100 / (1 + RS). Convert the RS into the RSI value to gauge the momentum as an index between 0 and 100.

Step 6: Analyze RSI

Interpret the RSI value to make trading decisions. An RSI above 70 may indicate an overbought condition, while an RSI below 30 may suggest an oversold condition.

Use Cases for RSI Calculation in Excel

Stock Price Momentum Analysis

Traders can analyze stock price momentum to make informed buying and selling decisions. By calculating RSI in Excel, investors can quickly identify whether a stock is overbought or oversold, helping them time their market entries and exits more effectively.

Custom Trading Strategy Development

Excel-based RSI calculations enable traders to develop and refine personalized trading strategies. This allows for the integration of RSI with other technical indicators to create comprehensive trading systems tailored to specific market conditions and risk preferences.

Portfolio Diversification Management

Investors can monitor the relative strength of different securities to optimize their portfolio allocation. By comparing RSI values across multiple assets, they can identify opportunities to rebalance their portfolios and maintain desired risk levels.

Trading Model Back-testing

Excel's RSI functionality allows traders to test their trading strategies using historical data. This enables them to validate their approach and fine-tune their trading parameters before risking real capital in the market.

Forex Market Analysis

Currency traders can identify overbought or oversold conditions in the forex market using Excel-based RSI calculations. This helps them spot potential reversal points and manage their currency pair trading positions more effectively.

Frequently Asked Questions

What is the basic formula to calculate RSI in Excel?

RSI is calculated using the formula RSI = 100 - (100 / (1 + RS)), where RS = Average Gain / Average Loss.

How do you calculate the daily gains and losses for RSI in Excel?

For daily gains, use the formula =IF(B7>B6,B7-B6,0) where B7 is the current closing price and B6 is the previous closing price. For losses, use =IF(B7

How do you calculate the average gains and losses for RSI?

First calculate a simple average using =AVERAGE(C7:C20) for the initial 14-day period. For subsequent periods, use an exponential average with the formula =((E20*13)+C21)/14.
