F&O Timing from October till 11:55 pm?

I tried taking an Options trade on 5th of October after 3:30 pm thinking that exchange will keep F&O segment open till 11:55 pm. Unfortunately, my order got rejected.

What’s the current timing s for futures and options? Is it till 3:30 pm or 11:55 pm?

Are brokers like Zeodha going to keep F&O trading open till late night?

LOL?

SEBI has deferred it, forget it for time being

ah okay… thanks for the news.
