Open interest (also referred to as open contracts or open commitments) refers to the overall range of spinoff contracts, like futures and options, that haven’t been settled within the straight off previous period of time for a selected underlying security. Nifty open interest conjointly means that the overall range of Nifty options and/or futures contracts that don’t seem to be closed or delivered on a selected day. Conjointly the amount of buy market orders before the stock exchange opens.
How to calculate Nifty Open Interest?
Nifty Open Interest measures the number of outstanding contracts at the tip of every day. Actually, Nifty Open Interest solely records half the outstanding contracts. For every buyer, there should even be a seller, however. This doesn’t have an effect on however we use open interest. Open Interest also can be taken because of the flow of cash coming into and exiting a market.
If Nifty Open Interest is increasing then this can be a symptom that there’s new buying going on. And traders expect this trend to continue. Conversely, if Open Interest is declining it shows that traders are taking their cash out of the market, or liquidating. Therefore the current trend can doubtlessly finish shortly. Similarly, if Nifty Open Interest decreases when prices advance, it’s a symptom that no new buying is going on and therefore the current uptrend is losing steam.

A practical example
On 28th November 2019, it was an expiry day for the Nifty index. So we checked at the OI figures before the market has opened. We saw the high puts were written at 12000 and 12050 levels. 12100 level has a neck to neck fight between the calls and puts and 12150 zone was holding shorts in call options. So we got a rough idea that expiry is likely between 12050 and 12150 zone. But will it be above or below 12100 zones, that will be decided by the intraday change of open interest chart?
Now as the market opened and trading started we saw put writing started on 12100 levels as the put bars started increasing in the Change of OI chart. Also, we saw call writing at 12150 zones. So we got an idea that the expiry will be between 12100 and 12150. So we will wait for a dip below 12100 to enter long. Or we will wait for a rally above 12150 to enter a short sell position. We will keep a 5 to 10 points room at both the zones for our entry. So our buying entry will be 12095-12105 and the short sell zone will be 12145 to 12155.
The market took a dip exactly at our buy zone and rallied upwards making big gains for 12100 call option buyers. You can also long the futures of the index but best to play with options for big gains on the expiry day.

Big volume bars can show that days had significant trading and on some other days trade was light-weight. The volume figure is often accustomed to verify the strength of this trend. If the volume is high or increasing, then the pressure behind the trend is high. Therefore the current trend is probably going to continue (up or down).
