An RSI reading of 30 or below indicates an oversold or undervalued condition.

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).
