Thanks, appreciate you writing on Sunday, and that too promptly. However, as expected, you have ignored the hard question. So will number them, in order to have a point to point response.
1. What do you consider ill-liquid stocks?
2. Stocks such as : Tata Motors / ACC / Infosys / Suzlon / Dena Bank etc. are (future stocks), which are highly liquid. Will you introduce market order for them as well along with Nifty?
3. Regarding the real life example given, it is really not apt to compare orders for stocks to options because even Nifty far OTM options will be illiquid.
