Questions
What is participant-wise open interest?
NSE publishes every evening how many F&O contracts are held long and short by four groups: clients (mostly retail traders), proprietary trading desks (Pro), foreign institutional investors (FII) and domestic institutional investors (DII).
What does FII index futures long % mean?
The share of FIIs’ index futures positions that are long, also called the FII long short ratio. On 19 Oct 2026 it was 10%. Very low readings mean FIIs are heavily short index futures, often as a hedge against their stock holdings.
