Here is the test this post applies to every criterion below. If you cannot check it on the exchange's website before the open, it is not a selection rule. It is an adjective.
Most advice on how to select stocks for intraday fails it. "Pick liquid stocks" and "avoid penny stocks" are both sound, and neither comes with a number you can look up.
Three things do.
How to Select Stocks for Intraday Trading?
Work through three published facts about a stock before you look at a chart.
How expensive it is to get in and out, how far it may move in a session, and whether it sits under a surveillance framework. The exchange publishes all three, and the rest is judgement.
Start your shortlist with measurable stock parameters using Stock Screener before moving to chart-based analysis.
Check Stock Liquidity and Trading Volume
Volume is a proxy, while impact cost is the measurement, and NSE calls it "the best measure of the liquidity of a stock".
It is the percentage mark-up you pay against the ideal price, which the exchange defines as the best buy and best sell averaged. NSE's example: 1,500 shares against an ideal price of 98.5 fill at 99.33, an impact cost of 0.84%.
That is closer to the true cost of execution than the bid-ask spread. For scale, a stock needs an impact cost below 0.50% to enter the Nifty 50.
Look for Stocks With Suitable Volatility
A stock needs room to move for a same-day trade to have anything to work with, and the exchange sets that room. Daily price bands run at 2%, 5%, 10% or 20% either way, depending on the security.
One category has none, because securities with derivative products carry no daily price band, which is why the F&O list is where most same-day activity sits.
Analyse Market and Sector Trends
A single stock does not trade in isolation. Index-based circuit breakers halt the whole market at 10%, 15% and 20% movement either way. Sector strength matters for the same reason: the tide moves the boat before your analysis does.
How to Select Stock for Intraday One Day Before?
The evening is when the checkable work gets done, because the exchange publishes it while the market is shut.
Look up impact cost, the applicable price band, and whether the stock appears on the ESM or GSM list, because those three answers do not change overnight.
What you cannot do the night before is know the price, so fix the criteria then rather than the trade.
Check News and Events Before Selecting Intraday Stocks
News moves price, and that is the obvious part. The less obvious part is that events can change the rules on a stock. Surveillance status, margin and price band can all shift, so a stock screened last week may not behave the same today.
Use Technical Analysis to Shortlist Intraday Stocks
No exchange or regulator publishes anything on whether particular indicators work for selection, so none is named here.
A technical shortlist narrows a large universe before the open, which is a real job and worth doing.
The constraint underneath does not move: the stock still has to be one you can leave at a predictable price. Intraday Trading Strategies covers execution.
Avoid Penny Stocks and Low Volume Stocks
This is not a judgement about the companies, but about what the exchange does to their shares.
The Enhanced Surveillance Measure applies to companies with a market capitalisation below ₹1,000 crore. Stage I carries 100% margin from T+2, and trade for trade settlement with a 2% or 5% price band. Stage II adds a 2% band under a periodic call auction.
The Graded Surveillance Measure goes further. Stage I is 100% margin and Stage II is trade for trade with a 50% additional deposit. At Stages III and IV a stock trades once a week.
A third list, the Additional Surveillance Measure, works on price variation and volatility. The exchange says inclusion is surveillance, not an adverse action.
Intraday Trading vs Delivery Trading explains what a settlement type changes for a same-day plan.
Create an Intraday Stock Watchlist
Build it from the checkable criteria rather than what moved yesterday. Anything failing impact cost, price band or surveillance status is off the intraday list before the open.
Keep it short enough to actually watch.
Risk Management After Selecting an Intraday Stock
Every criterion above is one criterion: whether you can get out.
Set the exit before the entry, and size the position so being wrong costs a known amount.
A stock meeting every published test can still go against you. Selection improves the odds of an orderly exit, not the outcome.
Key Points to Remember When Choosing Stocks for Day Trading
Check impact cost rather than trusting volume alone.
Check the price band, remembering F&O securities have none, and check the surveillance lists, treating a hit as a stop.
Then do the judgement work, knowing the published facts ruled out the worst.
Conclusion
Choosing a stock for a same-day trade is mostly filtering, and the exchange has published the filters. Impact cost tells you what liquidity costs, the price band tells you how much room there is, and the surveillance lists tell you what to leave alone.
All three can be checked the night before, on the exchange website, for free.
None of the three tells you whether the trade will work. That part carries the same risk of loss it always did.
