RSI Indicator : ( Relative Strength Index )

Overview

“Ups and Downs are part of our lives and part of the stock’s life too.” It is a well-known fact that the stock market is extremely volatile and dynamic. In the market, Relative Strength Index Indicators (RSI indicator) are used to measure the volatility in a particular stock’s price. The purpose of RSI indicator is to measure the recent price changes of particular stocks on a scale of 100.

This further helps traders or investors in making informed trading decisions. It is like the media of a particular stock, as it takes full notes of ups and downs. Further, it compares the price of a stock in both uptrend and downtrend, thus helping traders in forecasting the future movement of the stock.

Role of RSI Indicator:

RSI Indicator help in keeping track of price fluctuations and price trends of a stock on a graph of scale 1-100. The graph of this indicator helps immensely in identifying market sentiments and trends. They help significantly in determining the strength of price trends and points of reversal. Thus, known as momentum oscillators or momentum indicators. Momentum oscillators help in studying the speed or frequency at which the price is changing or fluctuating. 

The prime role of RSI indicator is to help traders in analyzing overbought and oversold situations. It also indicates the reversal of trends and a corrective pullback in the price of the stock. 

RSI is a useful tool in technical analysis, with appropriate analytical skills traders can know when to sell or buy the stock. As said the RSI indicator measures price on a scale of 1-100. When the RSI is near 30 or below, it indicates the situation when the stock is oversold. Whereas when the RSI is near 70 or above, it indicates the situation when the stock is overbought.

Interpretation of RSI Indicator:

• RSI makes it easy to spot the support and resistance zone in the candlestick chart of the stock. Many traders find it difficult to find patterns like a double top, or double bottom in the chart. Whereas, taking help from RSI Indicator makes it easier. 
  
• There are times when a new high or low is seen on the candlestick chart but it is not detected in its RSI index. This is called divergence and it often signals a reversal in price trend.
  
• If the RSI of a stock makes a smaller high and then drops below the previous low, then a downtrend is expected. This is called the Top Swing Failure. 
  
• If the RSI of a stock makes a higher low and then the price goes above the previous high, then the uptrend is expected. This is called the Bottom Swing Failure.

Overbought and Oversold Level:

Overbought and oversold levels indicate the unfair price as compared to the intrinsic value of the stock. 

Overbought level is when the trade value of the stock is above its fair and intrinsic value, it results in an unnecessarily high price of the stock. In this condition, the RSI of the stock is above 70. This often helps traders in forecasting reversal in an uptrend. Thus, they tend to sell the stock. 

An oversold level is when the trade value of the stock is below its fair and intrinsic value, it results in an unnecessarily low price of the stock.  In this condition, the RSI of the stock is below 30. This often helps traders in forecasting reversal in a downtrend. Thus, they tend to buy the stock. 

Hence, RSI can be a bullish indicator when it is oscillating on or below the level of 30. Whereas, it is considered a bearish indicator when it is oscillating on or above the level of 70.

Note: During strong trends, the RSI may remain oversold or overbought for longer than expected. A trader needs to have patience in such a situation to make profits out of it.

What is Divergence?

In earlier times, people used to identify the accurate support and resistance zones with the help of RSI. But as time passed, it gained popularity among traders and started trapping them by giving false signals. 

That’s when people understood the concept of divergence. Times when consecutive highs and lows are not formed similar to the RSI chart compared to the candlestick chart. Meaning, it is not necessary if the price is going from A (low point) to B (high point) in the price chart then similar will be with its RSI index. 

Often the price goes down in RSI despite the rise in its price chart. This indicates the reverse trend. Or vice versa in case of a downtrend. 

Suppose the price goes down 15 then to 10 and then to 5. But in the RSI after 10 the downtrend stops. This is called divergence. This signals the start of the uptrend in the candlestick chart. Vice versa happens in the downtrend.

Limitations of RSI Indicator:

Compared to all indicators RSI is one of the most reliable indicators for traders. But, in the past few years, RSI has become a prominent indicator and thus a lot of trapping in false signals has increased significantly. Be it short-term trends or long-term trends, both can be easily interpreted. A trader needs to learn the whole technical analysis well before making any move. Along with the good signal, there are also some false signals.

Calculation of RSI Indicator:
