My personal view is, after discussing the matter with few other experienced traders and one experienced person related with brokerage business,
as there is an only limited risk for BUY OPTION side SEBI can't use notional turnover for exposure calculation. The option is only the price of the premium. It'll be easily challenged in Court. It's difficult to prove such bogus logic in court.
But Intraday & positional option writing leverage and intraday and positional future trading leverage will be reduced drastically. Possibly, Intraday cash leverage will be automatically reduced if linked with ITR or networth.
It's also very hard to implement exposure in the delivery market, based on income/networth too,
bcoz a retired person may not have any income presently and not much liquid net worth too, but a big collection of stocks in his or her portfolio collected for several years.
No one can suddenly tell people to SELL your portfolio of stocks, there is a Court to protect a citizen's right against the implementation of such NONSENSE ideas.
