Open interest or OI is the total volume of open positions in the market. For example, if A is long on one lot of Nifty and B is short on 1 lot then the total open interest is calculated as one lot. Change in OI tells you if accumulation is happening or unwinding of positions is happening. It helps you to figure out what exactly is happening in the market and whether the accumulation or short covering is happening. This gives cues to the future movement of stock prices.
As the above table shows, it is clear how the OI has moved. But you must always correlate the OI shift with the change in the market prices as it gives you the precise picture of the market.

As the above table shows, it is clear how the OI has moved. But you must always correlate the OI shift with the change in the market prices as it gives you the precise picture of the market.
