Stock Market Guide All you need to know about TRIN Indicator

07 Dec 2023

Introduction:

Experienced stock market traders often emphasise their dependence on fundamental analysis, price charts, and various technical indicators. While focusing on the company's fundamentals is essential for long-term investors, intraday or swing traders often rely on technical indicators to speculate trends in the stock market, predict price movements, and make informed trading decisions.

In this article, you will learn about one of the most vital technical indicators in the stock market – the TRIN indicator. Traders use it to gauge the overall market strength at a given point in time by evaluating the relationship between advancing and declining stocks. This helps them anticipate short-term price movements, typically for intraday trading.

What is a TRIN indicator?

Richard Arms, a noted financial consultant, developed the Short-Term Trading Index or TRIN in 1967. He used this indicator to measure the overall market sentiments by comparing the relative strengths of market advances and declines (supply and demand). It helps traders identify potential trend reversals or continuations and make their trading decisions accordingly.

TRIN is calculated by dividing the advancing stocks by the declining stocks and then dividing that result by the advancing volume divided by the declining volume. 

Below is the formula for calculating TRIN:

TRIN = (Advancing Stocks / Declining Stocks) / (Volume of Advancing Stocks / Volume of Declining Stocks)

Here, “Advancing Stocks” refer to the number of stocks trading higher for the day, “Declining Stocks” refer to the number of stocks trading lower for the day, “Advancing Volume” is the total volume of advancing stocks, and “Declining Volume” is the total volume of declining stocks.

How do we interpret TRIN readings?

Understanding TRIN readings is crucial to gain insights into market sentiments and make accurate trading decisions. If the value of TRIN is 1.0 at a given point in time, it indicates that the market is in a neutral state. Traders can expect sideways movement in stocks over the short term, and hence, it’s best to avoid taking fresh positions during this period.

However, if the value of TRIN is above 1.0, it suggests that the volume is higher in declining stocks as the sellers are gaining control over the market. Traders can expect bearish movement for the short term, which means it can be a good opportunity to enter a short position. 

Conversely, if the value of TRIN is below 1.0, it suggests the volume is higher in the advancing stocks and the buyers are gaining control over the market. Traders can expect bullish momentum for the short term, which indicates that it can be a good opportunity to enter a new long position.

Spotting trend reversals

TRIN is often used to identify potential trend reversals in the market. When the value of TRIN reaches extreme levels, it can be a signal that the market is in the overbought or oversold territory. A high TRIN reading, typically above 2.0, may suggest panic selling and probably the bottom of the downtrend. It could indicate a potential reversal of the trend from bearish to bullish.

Similarly, a low TRIN reading, typically below 2.0, may suggest excessive buying and probably the top of an uptrend. It could indicate a potential reversal of the trend from bullish to bearish. As a trader, you can look for divergencies between TRIN and market price movements for confirmation of a trend reversal.

Advantages of using TRIN indicator

Below are the advantages of using the TRIN indicator for trading:

  • It provides traders with a profound understanding of the overall market sentiment
  • Traders can spot trend reversals or continuations
  • The calculation of the TRIN value includes volume analysis, which is a crucial technical indicator
  • It provides an overall picture of what’s going on in the market at a given point in time
  • TRIN can be used to confirm buy, sell, or hold signals

Limitations of TRIN indicator

The limitations of TRIN include:

  • It often provides false signals than any other technical indicator
  • TRIN cannot be a reliable technical indicator when used alone
  • TRIN readings are prone to fluctuations due to external factors

To conclude

While TRIN can be a valuable technical indicator to understand the overall market sentiments, it cannot be used alone. You must use it in conjunction with other technical indicators, such as moving averages, MACD, and RSI, to confirm your trading decisions.
