What is the Relative Strength Index (RSI)?
The Relative Strength Index (RSI) is a momentum indicator and it helps to measure the magnitude of recent price changes, which leads to evaluate overbought or oversold conditions in the price of a stock or other asset. The RSI is displayed as an oscillator and ranges from 0 to 100. Traditional interpretation and usage of the RSI are that values below 30 represent oversold conditions and values above 70 represent overbought conditions.

In simple words, RSI is a technical analysis indicator that measures the speed and change of price movements. The RSI oscillates between 0 and 100. The main features of the RSI are the overbought area above 70 and the oversold area below 30. When the stock is overbought, it means that it is expensive, and when it is oversold, it means that it is cheap.

The RSI was developed by J. Welles Wilder and first presented in his book "New Concepts in Technical Trading Systems" in 1978. The Relative Strength Index formula uses a particular time frame.
How does the RSI work?
The RSI is calculated using a formula that measures the magnitude of recent gains and losses over a specific period to evaluate overbought or oversold conditions in the price of a stock or cryptocurrencies.

The RSI oscillates between 0 and 100. The typical time frame for the RSI is 14 days, but it can be adapted to other time frames as well. The most important thing is to be consistent with the time frame you use.

In a bull market, the RSI is generally in the 40 to 90 range, with the 40-50 zone serving as support. The RSI is most often found between 10 and 60 during a market downturn or bear market, with 50-60 serving as resistance.

Your stops will change dynamically as conditions shift, and they won't be static unless you use a programmatic stop-loss. Stops will differ based on the RSI settings and the strength of the security's or market's underlying trend.
The use of RSI in cryptocurrencies
Similar to stocks, cryptocurrency prices also fluctuate even more. And just like stocks, there are momentum indicators for cryptocurrencies that help to measure the speed and change of price movements. And the RSI is one of the most popular momentum indicators when it comes to cryptocurrencies as well.

The main difference between the stock market and the cryptocurrency market is that the crypto markets are open 24/7, 365 days a year. This means that there are always opportunities to trade, regardless of what time it is. The RSI can be used on any cryptocurrency, but it is recommended to use it on the major ones such as Bitcoin, Ethereum, Litecoin, etc. Only because these cryptos are the most traded and have some sort of stability.
Why is RSI important for stock/crypto trading?
There are so many reasons why RSI is important. But the main reason is that it helps to identify market conditions
1. Interpretation
When it comes to stock and especially crypto trading, timing is everything. You need to buy assets when the prices are low and sell those assets when the prices are high. And this is where RSI comes in handy. It helps to identify overbought and oversold conditions, so you know when to buy or sell. When Wilder initially expressed his RSI, he suggested 14 days. This time frame is still used by many traders today, but some use shorter or longer time frames depending on their trading style
2. Momentum
RSI is all about the momentum of assets. This means that it measures the speed and change of price movements. It's extremely important because it helps to understand what will be the ideal time to enter or exit a trade. Without this information, you might end up buying when the prices are high or selling when they are low. When it comes to cryptos, it becomes even more important because cryptocurrencies fluctuate a lot.
3. Shows trading signals
Another key reason why RSI is important is that it can show trading signals. These signals are not always accurate but they give you a general idea about what's happening in the market. And this is extremely useful, especially for beginner traders who don't have a lot of experience.
4. Pattern breakout
We know that the formation of patterns is a fascinating aspect of chart building. A breakout occurs when any pattern, whether it's a reversal or continuation, reaches a specific point in time. This means that the prices have moved outside of a defined range. The RSI is a momentum indicator that evaluates the stock's relative strength over some time. This means that it can help to identify potential breakouts.
5. Failure indications
When it comes to trading stocks and cryptos, at some point you will face failures and this is completely normal because no one is perfect. But the good thing is that RSI can help to identify these failures. For example, if you see that the prices are consistently falling while the RSI is rising, this might be a sign that the prices will reverse soon. So you can use this information to your advantage and exit the trade before it's too late.
How do I calculate RSI?
Calculating RSI is not that hard but if you are a beginner, you might struggle at the beginning. Here is the formula for Relative Strength Index or RSI:

RSI = 100 – [100 / ( 1 + (Average of Upward Price Change / Average of Downward Price Change ) ) ]

The most commonly used time frame for RSI is 14 days, but other periods can be used as well such as 9 or 25.
Do I have to calculate RSI manually?
No, you don't! You don't have to calculate RSI manually because there are online tools that can make your job easier. All you have to do is enter the ticker symbol of the stock or cryptocurrency and the time frame that you want to use. And the tool will do the rest for you.
