What is the RSI? Find out the details of the Relative Strength Index indicator


What is RSI?

RSI (Relative Strength Index) is a relative strength index. It is an indicator used in technical analysis.

This is a useful tool in and is applied in trading: stocks, forex or even cryptocurrencies. With this indicator you will know a bullish or bearish signal.

The indicator was developed by a mechanical engineer J. Welles Wilder in 1978.

What does the RSI tell us?

First, let's take a look at the RSI formula!

RSI = 100 – [100 / ( 1 + (Average Change in Price Up / Average Change in Price Down) ) ]

From this formula we can see that the indicator shows the correlation between buyers and sellers. The RSI is shown from 0-100 and the balance will be 50.

In addition, you also know the overbought zone if the index goes above 70 (buyers dominate) and oversold if the index is below 30 (sells dominate).

This means that when the RSI crosses 70, the price is likely to turn around and fall. When the RSI is below 30, it shows that the selling force has decreased and the price is likely to rise again.

How to use the RSI

The most traditional and basic way to use the RSI is to consider selling when the index is above 70 and buying when the index is below 30.

But this is usually not very efficient. Because if it's that easy, how can anyone swing to the top, right?

Another simple way is to use the 50 level. In an uptrend market (bull market) the RSI will fluctuate between 40-90 with the 40-50 area being support. In a bear market, the RSI will range from 10-60 with the 50-60 area being resist.

There are also many ways to use this indicator in addition to the ways I mentioned above. To know, let's learn more with Blogtienao!
