why sensex is not in f&o like how nifty and banknifty is available
There are F&O contracts on Sensex, but those are hardly traded, you can check it out yourself here.
Are they open for trading in Zerodha? Or are they blocked, citing liquidity issues.
BSE F&O aren’t currently available.
Liquidity begets liquidity but not even having that option leads to ZERO liquidity.
In 2008-09 I remember sensex future was trading .It was having a lot size of 15 and it was not too liquid but better than nifty IT as far as liquidity was concerned. Gradually Bid Ask difference grew substantially and voloume kept on shrinking.
