Introduction

Why Open Interest Matters in Trading

1. Market Sentiment: Rising OI indicates that new money is flowing into the market, reinforcing trends. Conversely, falling OI suggests reduced participation and the possibility of a trend reversal. 
2. Liquidity Indicator: High OI ensures greater liquidity, making it easier to enter and exit trades without significant price impact. 
3. Trend Confirmation: When OI rises alongside price movements, it often validates the trend’s strength.

Using Open Interest in Strategies: -

1. Spotting Breakouts When OI and trading volume rise together during a price breakout, it confirms that the breakout is supported by strong market participation. This is a reliable signal that the trend is likely to continue. 
2. Identifying Reversals Divergences between price movements and OI can signal a potential reversal. For example, if a stock’s price rises while OI declines, it suggests waning market interest, indicating a possible reversal. 
3. Intraday Trading Tracking OI changes intraday can reveal institutional activity, often referred to as "smart money." Large increases in OI for specific contracts may indicate where significant market players are positioning themselves.
