What is the concept of the RSI index?
The RSI indicator is the abbreviation for the Relative Strength Index. This is a tool that measures the recent change in price. This indicator helps assess overbought and oversold conditions of stocks or other assets. In technical analysis, the RSI is represented in the form of a graph.

- An RSI of 70 or higher shows that the security is becoming overbought or overvalued. This is often a sign of an upcoming trend reversal and price correction.
- RSI values of 30 or below indicate oversold or undervalued conditions for that security.
- The RSI ranges between 30 and 70 is considered neutral, while a level of 50 is generally considered to indicate no particular trend.

Overbought RSI: When RSI crosses 70 and approaches 100. This is an overbought signal. This shows that the price is in an uptrend. This is also a sign that the market may decline in the future.
Oversold RSI: When RSI crosses 30 and approaches 0. This is an oversold signal. This shows that the price trend is down. At the same time, it is also a sign that the market may rise again in the future.
RSI Divergence (Divergence): RSI divergence appears in two forms: Relative Strength Index Bullish Divergence and RSI Bearish Divergence. Description as follows:
- RSI Bullish Divergence: When the price is falling and the Relative Strength Index line is rising, this is a strong signal for future price increases.
- RSI Bearish Divergence: If the price is rising and the Relative Strength Index line is falling, this is a sign that the price may fall sharply in the future.
Detailed Relative Strength Index calculation formula
How to calculate RSI as follows: RSI = 100 – 100/ (1+RS)
In which:
– RS: relative strength. RS = AG/ AL
AG: stands for Average Gain. This is the average of the total number of increasing periods in a certain period
AL: Stands for Average Loss. This is the average of the total number of decreasing periods in a certain period
– RSI is the closing price within the last 14 days.

To conveniently monitor and determine buying and selling power, traders often use the Relative Strength Index 30 and 70 thresholds as follows:
- Overbought: When the RSI line > 70.
- Oversold: When the RSI < 30.
Relative Strength Index predicts future trends
– An uptrend occurs when:
- RSI crosses the 50 threshold from bottom to top.
- RSI is in the range of 45 – 55 then increases to exceed 55.
– A downtrend occurs when:
- RSI crosses the 50 threshold from top to bottom.

Analyzing RSI indicator on time frames
Step 1: Find and identify the trend.
- The price will show the overbought or oversold level on the D1 time frame.
- When RSI < 30, this indicates that the market is changing from a downtrend to an uptrend and entering the oversold zone. At this time, you should switch to the H4 time frame to place a buy order.
- When RSI > 70, this indicates that the market has changed from an uptrend to a downtrend and entered the overbought zone. At this time, you should switch to the H4 time frame to place a sell order.
Step 2: Determine the entry point of the order on H4.
- After identifying the market trend, you need to switch to the H4 time frame to determine the buying and selling points.

- Place a sell order as soon as the price crosses the overbought zone on the H4 zone.

You can apply the Relative Strength Index indicator independently. You can also combine it with other indicators to achieve optimal results. To implement this concept, you need to perform the following steps:
Step 1: Create a horizontal line of the Relative Strength Index 50 line on the chart system.
Step 2: Place a buy order when RSI crosses the 50 level and at the same time SMA30 crosses above SMA100. In case the Relative Strength Index falls below 30 and the SMA30 falls below SMA100, stop trading.
For a sell order, you will place it when the Relative Strength Index is below 50 and the SMA30 crosses below SMA100. Close the order when SMA30 crosses above SMA100 and RSI rises above 70.
