What If...

ScenarioWhat you should know

I want more confirmation before interpreting an OI change.Compare Futures OI with volume, VWAP, or options data for additional context.
I want to place a trade after analysing Futures OI.Orders cannot be placed directly from the Futures OI chart. Use the relevant FYERS order-entry feature to place the trade.
