Understanding the Relative Strength Index (RSI)
The Relative Strength Index, often abbreviated as RSI, is a critical tool used in the trading world. This term might sound a bit complex if you're new to trading, but don't worry! By the end of this glossary entry, you'll have a strong understanding of what it represents and how to use it for your trading decisions.
What is the Relative Strength Index?
The Relative Strength Index is a momentum oscillator. In simpler terms, it's a tool that helps traders to identify when an asset is overbought or oversold. So, you may ask, "What does overbought or oversold mean?" When an asset is said to be overbought, it means its price might soon decrease. Conversely, if it is oversold, the asset's price is likely to increase.
How is the Relative Strength Index calculated?
The RSI is calculated using the average gains and losses over a specific period. Typically, the standard period for RSI calculation is 14 trading days. This number can vary depending on personal preference, but 14 is the industry standard. The actual formula for calculating the RSI might seem complicated, but fortunately, most trading platforms do this calculation for you.
How to interpret the Relative Strength Index
The Relative Strength Index gives readings from 0 to 100. Generally, a reading over 70 suggests that the asset is overbought, indicating its price may fall soon. On the other hand, if the reading is below 30, it shows that the asset is oversold, meaning its price might rise. These parameters are not set in stone and can be adjusted based on market conditions and trading strategy.
Using the Relative Strength Index in trading
The RSI is widely used not only to spot potential buying or selling opportunities but also to confirm trend formations, providing traders a strong advantage in making their decisions. When used in combination with other indicators, the RSI can be a powerful tool to support your trading decisions and manage risk.
