In short, the FII futures daily purchase is not equal to the change in futures. For example, here’s one such instance on 21st July.
Net buys in a contract can either result in squaring up an existing position or building a new position within that client category.
For example, the Rs 2147 crores in this image are the net buy for the day. But since the overall change in OI is just Rs 400 crore, the net buys activity is a result of squaring off or an earlier held position or transfer of earlier held positions.
From a category perspective, NSE publishes category-wise OI in F&O. The report has category-wise long and short OI for respective instruments. ( Click here to check the report for reference)
Category-wise net turnover should be compared with category-wise OI for drawing any inferences if any about market trends for the respective category.
