Market order buy/sell of index options

[kingsmasher1]

Hi All,

Zerodha supports Market-Order buy/sell of index options (Nifty and BankNifty), but they have their own basket of issues and technical glitches.
Can anyone help me to know which are the other brokers which supports market-order buy/sell of index options?

Mostly all options needs a limit order (including index), but i am looking for one in index where we can buy/sell in market-order.

Thanks in advance,
