The Relative Strength Index (RSI) is a technical indicator used to measure the strength and momentum of a financial asset's price movement. It helps traders identify overbought or oversold conditions in the market.
The RSI is calculated using a formula that compares the average gain and average loss over a specified period. The most commonly used time frame is 14 periods, but it can be adjusted to fit a trader's preferences.
To calculate the RSI, follow these steps:
- Determine the period length: Decide how many time periods you want to use for the calculation, typically 14 periods.
- Calculate average gains and losses: Determine the price difference between the current period and the previous period. If the difference is positive (gain), record it. If it is negative (loss), record the absolute value as a gain. Calculate the average gain and average loss over the designated period. Average Gain = (Sum of gains over the period) / (Number of periods) Average Loss = (Sum of losses over the period) / (Number of periods)
- Calculate the relative strength: Divide the average gain by the average loss. Relative Strength = Average Gain / Average Loss
- Calculate the Relative Strength Index (RSI): Use the formula below to calculate the RSI. RSI = 100 - (100 / (1 + Relative Strength))
The resulting RSI value is a number between 0 and 100. If the RSI value is above 70, it indicates that the asset is potentially overbought, suggesting a possible price correction. Conversely, an RSI value below 30 indicates oversold conditions, suggesting a potential price rebound.
Traders often use the RSI in conjunction with other technical analysis tools to confirm signals and make informed trading decisions. It's important to note that the RSI is not a standalone indicator and should be used in conjunction with other analysis techniques for more accurate results.

What is the difference between standard RSI and RSI divergence?
Standard RSI (Relative Strength Index) is a momentum oscillator that measures the strength and speed of price movements. It identifies overbought and oversold levels by comparing the magnitude of recent gains to recent losses over a specified time period.
On the other hand, RSI divergence is a trading signal that occurs when there is a discrepancy between the price action and the RSI indicator. It occurs when the price makes a new high or low, but the corresponding RSI reading fails to confirm the same high or low.
The key difference between the two is that standard RSI is used to identify overbought and oversold levels and determine potential trend reversals, while RSI divergence is used as a confirmation of a potential trend reversal or a change in momentum.
RSI divergence can be classified into two types:
- Bullish Divergence: Occurs when the price makes a lower low but the RSI indicator forms a higher low. It suggests a potential bullish reversal is likely to occur.
- Bearish Divergence: Occurs when the price makes a higher high but the RSI indicator forms a lower high. It suggests a potential bearish reversal is likely to occur.
In essence, while standard RSI is a standalone indicator that assists in identifying overbought and oversold conditions, RSI divergence is a complementary signal that traders use to confirm potential trend reversals.
How to set the RSI indicator on a trading platform?
The process of setting the RSI indicator on a trading platform may vary depending on the specific platform being used. However, here are general steps to set the RSI indicator on most trading platforms:
- Open your trading platform and locate the chart where you want to add the RSI indicator.
- Find the indicator menu or toolbar. This is usually located in the top or left-hand side of the chart, but the exact location may vary depending on the platform.
- Look for the RSI indicator among the list of available indicators. It is usually categorized under oscillators or momentum indicators.
- Once you have found the RSI indicator, click on it to select it.
- You will then be prompted to input the desired parameters for the RSI indicator. The default setting for the RSI is typically 14 periods, but you can customize it based on your preferences or trading strategy. Common values used include 9, 14, or 21 periods.
- After setting the parameters, click on the "Apply" or "OK" button to add the RSI indicator to your chart.
The RSI indicator should now be visible on your chart, usually displayed below the price chart as a line graph or histogram. You can adjust the appearance and color settings of the RSI indicator according to your preferences through the platform's customization options.
It is important to note that these steps are general guidelines, and the exact process may differ depending on the trading platform you are using. It is recommended to consult the platform's user guide or contact customer support for specific instructions on adding indicators.
How to interpret RSI values?
RSI (Relative Strength Index) is a technical analysis oscillator that measures the speed and change of price movements. It is especially useful for identifying overbought and oversold conditions in a market. The RSI values can range from 0 to 100, and the interpretation of these values is as follows:
- Overbought Levels: When the RSI value exceeds 70, it suggests that the market or security may be overbought. This could indicate that the price has risen too quickly and is due for a potential reversal or a pullback in the near future. Traders might consider selling or taking profits in such situations.
- Oversold Levels: When the RSI value falls below 30, it suggests that the market or security may be oversold. This could indicate that the price has fallen too quickly and is due for a potential reversal or a bounce back in the near future. Traders might consider buying or entering long positions in such situations.
- Divergence: Another way to interpret RSI values is by looking for divergences. If the price of a security is making higher highs but the RSI is making lower highs, it indicates a bearish divergence, suggesting a potential reversal or a downward move. Conversely, if the price is making lower lows but the RSI is making higher lows, it indicates a bullish divergence, suggesting a potential reversal or an upward move.
- Trend Confirmation: RSI values can also be used to confirm the strength of a trend. Generally, if the RSI value is above 50, it indicates that the price is in an uptrend, and if it is below 50, it suggests a downtrend. Traders might look for bullish signals in an uptrend when the RSI crosses above 50 and bearish signals in a downtrend when the RSI crosses below 50.
Note that RSI values should not be solely relied upon for decision-making but should be used in conjunction with other technical indicators and analysis tools to confirm signals and make informed trading decisions.
What is the role of RSI in determining market strength?
RSI, which stands for Relative Strength Index, is a technical indicator used by traders and investors to determine the strength or weakness of a market. It is based on the concept of momentum and measures the speed and change of price movements.
The primary role of RSI is to identify overbought and oversold conditions in a market. It indicates whether an asset is potentially overvalued or undervalued, which can help traders make informed decisions regarding buying or selling.
Typically, a market is considered overbought when the RSI value is above 70, suggesting that the asset may be due for a correction or a downward movement. Conversely, an RSI value below 30 indicates an oversold condition, implying that the asset may be undervalued and could potentially rebound or rise.
In addition to overbought and oversold conditions, the RSI can also provide insights into market trends and confirm the strength or weakness of a trend. For example, if the RSI is rising along with the price, it suggests that the market is strong, and the uptrend is likely to continue. Conversely, if the RSI is falling while the price is rising, it may indicate a potential weakening of the market trend.
However, it is important to note that RSI should not be used as the sole factor in determining market strength. It is just one tool among many others used by traders, and it is often used in conjunction with other indicators and analysis techniques to make informed trading decisions.
