Market Orders for Stock options

Which stock options are allowed for market order placement at zerodha?

Hi @gautam_pinjani
Market orders are blocked for illiquid index options and all stock options.

Market orders are restricted for certain contracts due to liquidity concerns. Illiquid contracts may have bid/ask prices that differ significantly from the last traded or theoretical prices. Placing market orders without considering these bids/asks can lead to unfavourable trade execution and potential losses.
