RSI Calculation Formula
- RSI = 100 – 100 / ( 1 + RS )
- RS = Relative Strength = AvgU / AvgD
- AvgU = average of all up moves in the last N price bars
- AvgD = average of all down moves in the last N price bars
- N = the period of RSI
- There are 3 different commonly used methods for the exact calculation of AvgU and AvgD (see details below)

What is RSI based on?
What is the RSI indicator? The RSI indicator buy and sell signals are based on oversold and overbought conditions on a stock chart. The RSI is a measurement of price moving too far and too fast in one direction and as the RSI gets extended farther from the 50 RSI middle line the probability of a reversion to that mean increases.
How do you calculate RSI for a stock?

What is RSI indicator?
Well the RSI is one of the most popular indicators of choice by traders around the world. The term ‘Relative Strength Index’ must not be confused with ‘relative strength’ which is when we compare one stock against another or one sector. The RSI, like most indicators is the calculation of averages, this is what the calculation looks like.
What is RSI used for?
The RSI is used as over bought and over sold indicators, divergences and even centerline crossover. Since the indicator is normalised and bounces between 0 and 100 it can be used to initiate trades using the techniques mentioned above.
What is the average time period for RSI?
The average time period we use for the RSI is the 14 period average. Let’s say in the last 14 days, there were 10 up days and 4 down days. We will take the average gain on the 10 days and divide it by 14 – then use the average loss of 4 days and divide it by 14.
Step 1: Calculating Up Moves and Down Moves
We’ll illustrate the calculation of RSI on the example of the most common period, 14. For RSI calculation you need closing prices of the last 15 days (for RSI with a period of 10, you need the last 11 closing prices etc.).
Step 2: Averaging the Advances and Declines
Three different approaches are commonly used. They differ in the way how average up and down moves are calculated:
Step 3: Calculating Relative Strength
Now as you have the average up move (AvgU) and average down move (AvgD) in the last 14 price bars, the next step is to calculate Relative Strength, which is defined as the ratio of average up moves and average down moves.
Step 4: Calculating the Relative Strength Index (RSI)
Finally, we know the Relative Strength and we can apply the whole RSI formula:
Lowest Possible RSI Value
What situation in the market would give us the lowest possible RSI value? A totally bearish market, of course. Imagine that every single day the market closed lower than the day before. There would be no up days (all the U’s in the last N bars would be zero).
Highest Possible RSI Value
What situation in the market would give us the maximum possible RSI value? This would be a totally bullish market with no down days. AvgD would be zero, AvgU some positive number. Relative Strength would be something positive divided by zero. Mathematically, you can’t calculate this – in this case the RSI value is defined as 100.
Comparing the Calculation Methods
The three calculation methods often give quite different results. While different traders have different preferences, most would agree that being consitent and sticking with one method (rather than jumping from one to another) is more important than which of the methods you choose (this also applies to RSI period length).
