I guess the heuristic we can use is to basically treat 3:20 as the market close and stop looking at it.
Then in the morning, just combine the CAS and the pre-session as the combined pre-market thing and then trade. Because right after cash, the options won’t move anyway, right? So basically treat the cash session and the pre-session as a combined pre-market thing and just trade in the morning.
P.S. It works for somebody who doesn’t trade expiry days or expiry week.
But exchanges won’t treat the same. For example, if today was nifty expiry, nifty closed 200 points up and your F&O would be treated at that close. If you sold 24600, you basically lost 200 points in 15 minutes.
Questionanble as who is really buying into this? The market literally ignored the move as a whole. I even think market liquidity makers themselves were stunned as to how to handle this.
But i could be wrong! Who knows what if our govt joined hands with JS. they would need some humongous money for next elections to win!
Hopefully this was only some unforseen correctable glitch that NSE had while deploying the new system… and will not repeat…
Sensex closed well. If this NSE issue shows tendency to happen tom, arbiters will rush in and establish new equilibrium. But that could also lead to some erratic pricing in the interval - so hope NSE fixes things their end.
NSE clearly said this wasn’t a glitch. This will be the norm going forward. Even if this doesn’t happen again for the next week or so, you should assume this is what JS is capable of and can do so any time at will - this is just testing for them.
Yesterday coz of sudden spike today all brokers increases margin on CE sell side .
Today morning it was just price adjustment but it is being shown as gap down
Again tomorrow margin will increased on wrong side just coz of price discovery! Whole day there is time to discover the price but some idiot designed this price discovery in last 15 mins . Plus additional 15 mins .
So its like weekly options expiry shifted to daily expiry. Now everyday no one knows what actually happens . System designed to cheat and rob in day light .
