What is the Relative Strength Index (RSI)?

The Relative Strength Index (RSI) is a momentum oscillator used in technical analysis that measures the speed and change of price movements.

RSI helps traders identify overbought or oversold conditions in the price of a cryptocurrency or other assets.

RSI values range from 0 to 100, with:

• Overbought conditions typically indicated by an RSI value above 70.
• Oversold conditions suggested by an RSI value below 30.

These thresholds help traders predict potential reversals, as they suggest that an asset's price might have extended too far in a direction and could be due for a correction.

How Does RSI Work?

RSI calculates momentum as the ratio of higher closes to lower closes. Assets with more or larger positive changes have a higher RSI than those with more or larger negative changes. The formula for RSI involves several steps but fundamentally focuses on average gains and losses over a specified period, typically 14 days.

1. Calculate the Average Gain and Average Loss: Over the chosen period (commonly 14 days), determine the average of all up closes and the average of all down closes.
2. Compute the Relative Strength (RS): This is the ratio of average gain to average loss.
3. Normalize the RS to obtain the RSI: The formula is RSI = 100 - (100 / (1 + RS)).

Don't worry most exchanges and tools compute this automatically. So you don't have to know this formula. Let's put this to practice.

Not to Be Confused with the Moving Average (MA)

While RSI measures price momentum and potential market reversals by identifying overbought and oversold conditions, the Moving Average (MA) is a trend-following indicator. MA helps smooth out price data over a specified period, giving a clearer picture of the price trend without the short-term fluctuations. It is calculated by averaging the price of an asset over a specific number of periods. For more on how MAs can guide your trading decisions, you can learn more about Moving Averages here.

Using RSI in Trading: A Practical Example

To illustrate how RSI can guide trading decisions, let’s consider a hypothetical example involving Bitcoin (BTC).

Scenario: Suppose Bitcoin has been on a consistent upward trend, and you're monitoring its RSI to determine the right moment to sell.

1. Identify the RSI Level: You notice that BTC’s RSI climbs above 75, indicating an overbought condition.
2. Decision Point: Historically, when RSI levels are this high, BTC tends to correct or pull back. As a trader, you might see this as an opportunity to sell before a potential dip.
3. Action: You decide to sell a portion of your BTC holdings based on the RSI indication.
4. Outcome: Following the RSI signal, BTC experiences a correction, confirming that the overbought signal was a reliable indicator to sell.

Conversely, if you were looking to buy and noticed the RSI dropping below 25, signaling oversold conditions, you might prepare to purchase BTC, anticipating a price rebound.

The Relative Strength Index is a versatile and essential tool in your trading toolkit, especially in the volatile crypto markets. By understanding and applying RSI, you can make more informed decisions, potentially enhancing your trading outcomes. While RSI is powerful, it’s most effective when used in conjunction with other indicators and a comprehensive trading strategy.
