Is Open Interest keyword working?

I want to create a strategy based on OI of certain strikes, but when I use OI keyword strategy does not work

Hi,

Open Interest Keyword is not active as of now.
However, Max OI Strike, Max OI Instrument, Total OI and PCR are active but for Indexes Only

What if I want to select a strike which 1 strike below or above the MAX OI Strike?

Short answer: the plain Open Interest keyword is not operational. Use Max OI Strike, Max OI Instrument, Total OI or PCR instead.

• They work on index options only: NIFTY, BANKNIFTY, MIDCPNIFTY, FINNIFTY, SENSEX.
• Underlying must be the bare name ('NIFTY', not 'NIFTY 50'). Expiry must be the literal 'current month' or 'current week' (weekly only for NIFTY and SENSEX). A wrong value validates fine but returns nothing.
• There is no per-strike OI keyword. Only these aggregates exist.

One strike above/below the Max OI strike (answering #3)

In Strike Fx, use Max OI Strike and add or subtract one strike interval:
Max OI Strike ( 'NIFTY', 'current month', 'CE' ) + Number ( 50 ). Check the current strike interval on the option chain. Do not assume it.
