Bombay Stock Exchange (BSE Ltd): Bet on Financialization?

Yes exactly. Twitter is full of frustation of 0 & 1 DTE players. Today’s sensex option premium turnover also suggests that many traders stayed away from playing sensex 0 DTE.

I was oserving options prices & there was no decay at all, infact from morning low straddle prices started going up despite index is silent, which kills option sellers who come for theta decay. Even at 3:15 straddle price was like around 400-500 rs. which is insane. & then after 3:15 blind game starts & then suddenly one price comes for settlement & entire decay occurs in few seconds.

If this CAS doesn’t gets smooth, it can ruin majority derivative business of BSE which is 0 DTE.

Fingers crossed.

As expected, BSE’s trading volumes dropped by more than 50% yesterday on weekly expiry day.

average number of contracts traded on weekly expiry dropped to just 25.5 crore contracts, a steep reduction of 52% within a few days of CAS going live

0DTE trading volumes will literally die now; Brokerages and exchange income will be hit badly
Also NSE IPO may be delayed or valuations will melt

I think the market participants are trying to understand the CAS system post which it will stabilise. Extrapolation of short term data to long term results maybe a little bit of a stretch. We should give time for the system to stabilize.

I am a full time day trader, i mostly do intraday with options and expiry trades.

There is no way in gods earth that i would sell options after the introduction of CAS, until CAS is removed at least for expiry days , i will not write options, there are millions like me , SO BSE and NSE volumes will definitely get affected big time.

option expiry need to be delinked from CAS.

Not only exchanges , but brokers will be hit hard, and Nirmala mam can kiss good bye to the 57,000 crores that they used to collect every year through STT and other taxes .alteast half of it

When will this take effect?

Index inflows would mean price going up.

It will be effective from September 30th
