What is the Relative Strength Index (RSI)?

If you’re into stock trading, you’ve probably heard of the Relative Strength Index (RSI). But what does RSI mean in the stock market, and how can it help you? RSI is a momentum indicator that shows whether a stock is overbought or oversold. The Relative StrengIt helps to see if a stock is either overbought or oversold. Traders use it to decide when to buy or sell a stock. 

By understanding RSI, you can make smarter trading decisions. This blog will explain what RSI is, how it’s calculated, why it’s important, and how to check the RSI of a stock easily.

Features of RSI

The Relative Strength Index (RSI) is widely used by traders due to its simplicity and effectiveness. Here are the key features of RSI:

• RSI Scale: Ranges from 0 to 100.
• Overbought Signal: RSI above 70 indicates the stock might be overbought.
• Oversold Signal: An RSI below 30 suggests the stock might be oversold.
• Timeframe Flexibility: Typically calculated over 14 days but can be adjusted.
• Momentum Indicator: Measures the speed and change of price movements.
• Helps Identify Reversals: Traders use it to spot potential trend changes.
• Widely Used: Commonly applied in both short-term and long-term trading strategies.

How to Calculate Relative Strength Index

To calculate the Relative Strength Index (RSI), use the following formula:

RSI = 100 – (100 / (1 + RS))

Where RS (Relative Strength) is calculated as:

RS = Average Gain / Average Loss

Here’s how to calculate it step by step:

Step 1: Find average gain and average loss

Choose a period, often 14 days. For each day the stock price increased, calculate the gain and then find the average gain over those days. Do the same for the days when the stock price dropped to find the average loss.

Step 2: Calculate RS (Relative Strength)

Divide the average gain by the average loss. This gives you the relative strength, which shows how much the stock has gained compared to how much it has lost.

Step 3: Apply the RSI formula

Plug the RS value into the RSI formula to get a result between 0 and 100.

RSI above 70 means the stock might be overbought, and below 30, it could be oversold. This simple calculation helps traders decide whether it’s a good time to buy or sell a stock.

Example Calculation

Let’s say a stock has gained an average of 2% over the last 14 days and lost an average of 1%:

RSI = 100 – [100 / (1 + (2/1))] = 66.67

In this case, the RSI of the stock is 66.67, suggesting it is approaching an overbought level but has not yet crossed the 70 mark. This means that while the stock is gaining momentum, it may not be a strong signal to sell just yet, but it’s important to keep an eye on further movements.

How Does the Relative Strength Index Work? 

The Relative Strength Index (RSI) works by comparing recent gains and losses in a stock’s price over a set period, typically 14 days. It looks at how fast and how much the stock’s price has changed to figure out if it’s becoming overbought or oversold.

RSI is calculated using a simple formula that gives a value between 0 and 100. If the RSI is above 70, it means the stock may be overbought, suggesting its price could fall soon. If the RSI falls below 30, it may indicate the stock is oversold, meaning its price might go up.

Traders use RSI to identify good entry and exit points for trades. A high RSI might signal it’s time to sell, while a low RSI could indicate a buying opportunity. It helps traders make decisions based on data rather than emotions, making it a valuable tool in the stock market.

How to Check the RSI of a Stock

Checking the RSI of a stock is simple. Most stock trading platforms show the RSI value for each stock. You can usually find this value in the technical indicators section of the stock’s profile.

Steps to Check RSI on Popular Platforms

1. Open Trading Platform: Start by logging into your favourite stock trading platform.
2. Find the Stock: Use the search feature to locate the stock you want to check.
3. Go to Technical Indicators: Look for a section labelled “Indicators” or “Technical Analysis” in the stock’s profile.
4. Select RSI: From the list of available indicators, select “RSI” to see the current RSI value for that stock.
