Despite much of the hype around AI, the technology has yet to dramatically reshape the way many businesses operate, or deliver meaningful returns.
Why?
I asked @McKinsey senior partner Asutosh Padhi, who advises CEOs on AI strategy and innovation:

🇺🇸 The USA is easy to visit. Planning it well is a different story.
Before you book that flight, read this.
I’ve packed my learnings, money-saving tips and practical tips from the trip into one guide.
Hope it makes your USA trip a little easier. 👇 https://t.co/8s8hGtWwOZ
Nine years ago, I quit my job to trade full time. Every reel you scroll has someone standing in front of six monitors telling you to take the leap, follow your passion, escape the nine to six. Very few of them tell you what the actual reality
So let me tell you honestly. 🧵
@vivbajaj CAS works against writers who earn on theta decay, but CAS may work on buyers who dream of zero to hero gains. The retailers who loose money to large operators are low on funds and hence buyers and are most vulnerable. This will impact vulnerable small retail buyers even more.
@vishalmehta29 The bid ask price of option is 0.01 ?
I can understand a buy order but who wd place a sell order?
I am unclear, can you please explain this large transaction please ? 🙏🏼
@ZerodhaVarsity Could you suggest a safe game plan for retail traders after 3pm. ? Shd they simply exit the trades during expiry days ( what about non expiry days ?)
The new Closing Auction Session (CAS) goes live for stocks in the F&O list today. Here are the important things to know👇
- Stocks in the F&O list: Continuous trading will stop at 3:15 PM, followed by CAS until 3:35 PM.
- All other stocks: Trading will close at 3:30 PM.
- Index and stock F&O contracts: Trading will close at 3:40 PM.
If you are trading intraday using the MIS product type, these will be the auto square-off timings from today:
- Equity (stocks under CAS): 3:10 PM
- Equity (stocks not under CAS): 3:25 PM
- Index and stock F&O contracts: 3:26 PM
To check which stocks trade in the F&O segment, add the “NSE F&O Stocks” list to your marketwatch on Kite or check them here: https://t.co/1BvJsjrKGy
Here’s a breakdown of how CAS works:
3:00 PM to 3:15 PM: Reference-price calculation
Regular trading will continue as usual.
During these 15 minutes, the exchange will calculate the VWAP of all trades in the stock. This will become the reference price for the closing auction.
3:15 PM to 3:20 PM: Transition to CAS
At 3:15 PM, regular trading will end for stocks under CAS. No new orders can be placed during this five-minute transition period. The exchange will calculate the reference price and set a CAS price band of ±3% around it.
For example, if the reference price is ₹1,000, orders during CAS can generally be placed between ₹970 and ₹1,030.
Unexecuted limit orders from regular trading will be carried forward into CAS. However, stop-loss orders and orders outside the CAS price band will be cancelled. Futures orders placed outside the applicable price band will also be cancelled. This does not apply to option orders.
3:20 PM to 3:25 PM: Market and limit order entry
During this period, traders can place, modify, or cancel both market and limit orders.
3:25 PM until the random close: Limit orders only
From 3:25 PM, new market orders can no longer be placed. Market orders placed earlier cannot be modified or cancelled.
Limit orders can still be placed, modified, or cancelled.
The order-entry period will close randomly between 3:28 PM and 3:30 PM.
3:30 PM to 3:35 PM: Order matching
After order entry closes, no new orders will be accepted.
The exchange will calculate the equilibrium price—the price at which the highest quantity of shares can be traded. All executable orders will then be matched at this single price. This will become the stock’s official closing price.
This is how order matching happens:
- Market orders get priority over limit orders.
- Eligible market orders are first matched with one another based on the time they were placed.
- Any unmatched market orders are then matched with eligible limit orders using price-time priority.
- Finally, the remaining limit orders are matched with one another, again using price-time priority.
What the hell is happening to the Indian stock market?
Dear @SEBI_India & @NSEIndia@BSEIndia
How many times do you expect traders to rebuild their entire business?
> December 2020 – 50% leverage removed
> March 2021 – 75% leverage removed
>September 2021 – 100% leverage removed
We adapted.
Yes, leverage is a double-edged sword. But thousands of genuine traders with smaller capital were affected. Still, we adapted.
> September 2023 – Bank Nifty expiry was shifted from Thursday to Wednesday, while BSE launched Sensex weekly expiry on Friday. Suddenly, we had expiries almost every trading day.
Many traders, especially algo and 0-DTE traders, redesigned their entire systems.
We adapted.
> November 2024 – Weekly expiries of FinNifty, Bank Nifty and other indices were removed. Only Nifty and Sensex weekly expiries remained.
Again, thousands of traders had to change their strategies.
We adapted.
> February 2025 – Expiry-day margin benefit was removed.
STBT traders were hit badly.
We adapted.
> 1st September 2025 – Nifty expiry shifted from Thursday to Tuesday.
Again...
We adapted.
> Jane Street reportedly made billions of dollars from Indian markets over the years. Later, regulatory action was taken, and subsequently trading restrictions were lifted after payment of regulatory dues/settlement.
How exactly did all of this benefit Indian retailers?
Meanwhile...
- Option STT has increased massively over the last few years.
- Bid-ask spreads have widened.
- Slippage has increased.
- Global volatility has increased.
- Transaction costs keep rising.
We adapted to everything.
And now...
Closing Auction Session (CAS).
Seriously?
Every few months there's another structural change.
Every few months traders are forced to rebuild their systems.
Every few months liquidity takes another hit.
You say these changes are for retail investor protection.
Then please show us the data.
Can you show even one report proving that retail trading losses have actually reduced because of all these interventions?
If not, then what exactly are these constant changes achieving?
Instead of making markets more efficient, you're making trading more expensive, more complicated, and pushing serious traders towards crypto and international markets.
As a full-time trader, my inner soul genuinely cries today seeing the direction our markets are heading.
We survived leverage removal.
We survived daily expiries.
We survived removal of daily expiries.
We survived expiry changes.
We survived removal of expiry margin benefits.
We survived higher STT.
We survived wider spreads and slippage.
Now we are expected to survive CAS as well?
Enough is enough.
I request SEBI and the exchanges to reconsider this rule.
Before implementing such major structural changes, consult the trading community. There should be proper communication, public discussion, and representation from active traders.
I also request every trader to raise their voice through the proper channels. If you genuinely believe these changes are hurting market participants, please send your feedback or complaint to SEBI through its official grievance mechanism. And if anyone from the industry has a direct channel to the exchanges or regulators, please help convey the concerns of the trading community.
Please Retweet this so our voice reaches the right people.
Enough of silent adaptation. It's time the trading community is heard.
