Quick Answer

To select stocks for intraday trading, look for high liquidity, meaning volume above 10 lakh shares a day, enough volatility measured by ATR of at least 1.5 percent of price, a tight gap between the buy and sell price, and presence in the F&O segment while staying off the F&O ban list. SEBI data shows nearly 88 percent of individual derivatives traders lost money in FY26, so stock selection alone will not save you without a fixed risk per trade rule, the right trading hours, and a clear grasp of intraday costs and taxes.

What Is Intraday Trading

Intraday trading means buying and selling the same stock on the same day. The position closes before the market shuts at 3:30 PM, no shares land in your demat account, and if you forget to close it yourself, your broker squares it off automatically, usually with an extra charge attached.

An investor buying for the long term can pick a good business and hold it through rough patches. An intraday trader does not get that luxury. There are only a few hours to work with, so the stock needs to behave in a specific way during those hours. It needs to move enough, trade easily, and not get stuck in a wide price gap. A strong company on paper can still be a poor intraday pick if it is not trading that way today.

How to Select Stocks for Intraday Trading Step by Step

Stock selection for intraday trading is a filtering exercise. You start with the full market and narrow it down using fixed checks instead of picking a stock because it looks like it is moving.

Check liquidity first. Liquidity is how easily a stock can be bought or sold without moving its own price. Look at average daily volume. Large cap names like Reliance Industries and SBI regularly trade 80 to 150 lakh shares a day. HDFC Bank and ICICI Bank usually stay in a similar range. As a floor, most traders avoid anything below 10 lakh shares a day in the cash segment.
Look at traded value, not just volume, and pick a threshold that matches your size. A stock trading a large number of shares at a very low price can still have thin traded value. Multiply volume by price. A turnover of roughly 100 crore rupees a day is a reasonable minimum for smaller retail positions, but traders working with larger capital, or sticking strictly to large caps, often set the bar closer to 400 to 500 crore rupees a day for extra safety on exits.
Measure volatility using ATR. ATR, or Average True Range, shows how much a stock typically moves in a day, in price terms. Convert it to a percentage of the stock price to compare across stocks. A stock moving less than 1 percent a day rarely leaves enough room for profit after costs. Stocks with higher beta, such as Adani Enterprises and Bajaj Finance, tend to swing more in a session than lower beta names like ICICI Bank, so they need tighter stop loss levels to match.
Stay within the F&O list and off the ban list. Stocks in the F&O segment usually have better depth because institutions trade them actively. NSE also places certain F&O stocks under a temporary trading ban when open positions cross a set limit, known as the market-wide position limit. Trading a banned stock intraday is not blocked outright, but liquidity and price gaps on that name often turn erratic during the ban, so it is worth checking the exchange website before building a position.
Check the gap between the buy and sell price. A gap under roughly 0.05 percent of price on a large-cap stock tells you buyers and sellers are close together. A wide gap means you lose money the moment you enter, before the stock has even moved in your favour.
Look for a reason the stock is moving, not just that it is moving. A stock can be liquid and volatile and still drift sideways all day if nothing is actually driving it. Before shortlisting a stock, check if there is a catalyst behind today’s move, such as quarterly results, a large order win, a rating upgrade, a sector-wide trigger, or a strong global cue in that stock’s sector.
Confirm the stock is moving with its sector. If Bank Nifty is trending up and your shortlisted bank stock is moving the same way, that is one more thing supporting your trade. A stock moving against its own sector without a clear reason is harder to trust.
Rule out stocks with pending, unrelated news. Skip stocks going into quarterly results, board meetings, or regulatory announcements later that same day, unless you are specifically trading that event with a plan for the extra risk.
Trade within the hours that actually favour intraday moves. The first hour after the open, roughly 9:15 to 10:30 AM, and the last stretch before close, around 2:30 to 3:20 PM, usually carry the cleanest volume and the sharpest moves. The stretch between late morning and early afternoon tends to be choppier and range-bound, which is a harder period for a beginner to trade well. Many traders wait 10 to 15 minutes after the open before entering, since the first few minutes can be erratic.
Fix your stop loss and size before entry, not after. Decide your exit level and position size so a loss on this one trade stays within about 1 to 2 percent of your total trading capital. Good stock selection reduces risk. It does not remove it.

Tools That Make Stock Selection Easier

Manually checking every filter on every stock is not practical each morning. A few free tools speed this up.

NSE pre-open and heatmap pages show which stocks are gapping up or down before the market opens, and which sectors are leading for the day.
Chartink lets you build a screener with conditions like volume above a set number, price change percentage, and ATR, so the filtering from steps one to three above runs automatically each morning.
The NSE F&O ban list page takes ten seconds to check and rules out step four in one look.
VWAP, or Volume Weighted Average Price, on the chart is a quick confirmation tool once a stock has passed the filters above. Price holding above VWAP through the morning generally supports a long bias, and holding below it supports a short bias.
The opening range, meaning the high and low band of the first 15 to 30 minutes, works the same way. A break above that range with volume is a common trigger many traders use to time entry into an already shortlisted stock.

None of these replace judgment, but they cut the time spent scanning the market from an hour to a few minutes.

Practical Example With Numbers

Priya, a trader in Chennai, has 1,00,000 rupees in her trading account. She shortlists two stocks after her morning screen.

Reliance Industries:

Price: 2,850 rupees
Average daily volume: about 90 lakh shares
Daily traded value: roughly 2,500 crore rupees
ATR: about 1.6 percent of price
Gap between buy and sell price: about 0.40 rupees, or 0.014 percent

A thinly traded small cap stock:

Price: 38 rupees
Average daily volume: about 70,000 shares
Daily traded value: roughly 27 lakh rupees
ATR: about 3.8 percent, but erratic
Gap between buy and sell price: about 0.45 rupees, or 1.2 percent

The small cap looks more volatile on paper, but a 1.2 percent price gap means Priya loses money on entry and exit before the price even moves her way. Reliance, despite a lower ATR percentage, is cheaper to trade because of its depth and tight price gap.

She waits until 9:30 AM, checks that Reliance is trading above its VWAP with the broader energy sector also in the green, then enters.

Using five times intraday margin, she buys 170 shares worth 4,84,500 rupees by putting up roughly 96,900 rupees as margin.
Stop loss is set at 2,822 rupees, 1 percent below entry.
Target is set at 2,907 rupees, 2 percent above entry.
If the target is hit, gross profit equals 170 multiplied by the difference between 2,907 and 2,850 rupees, which comes to 9,690 rupees.
If the stop loss is hit, gross loss equals 170 multiplied by the difference between 2,850 and 2,822 rupees, which comes to 4,760 rupees.

That is roughly a one to two risk to reward setup, before subtracting brokerage, STT, and other charges, which is exactly where the next section matters.

Costs and Tax on Intraday Profit

Costs eat into intraday profit faster than most beginners expect, especially on trades with small percentage moves.

Brokerage: usually 20 rupees or 0.03 percent per executed order, whichever is lower.
STT, the Securities Transaction Tax: about 0.025 percent on the sell side only for intraday equity.
Exchange transaction charge: a small percentage of turnover, roughly 0.00297 percent on NSE.
GST: 18 percent on brokerage and exchange charges combined.
SEBI charges and stamp duty: negligible per trade, but they add up over many trades a month.

On Priya’s Reliance trade above, these charges together would run into a few hundred rupees on entry and exit combined, meaningful enough that it should be checked before assuming the full 9,690 or 4,760 rupees is the final number.

On tax, intraday trading profit is treated as speculative business income under Section 43(5) of the Income Tax Act, not capital gains. It gets added to total income and taxed at your regular income tax slab rate. There is no flat or concessional rate. It also requires the ITR 3 form, not the simpler ITR 1 or ITR 2 forms used for salary or capital gains. If the trade results in a loss, that loss can only be set off against other speculative income, not salary or capital gains, and it can be carried forward for up to four assessment years.

This is general information, not tax or investment advice. Speak with a qualified tax professional for your specific situation.

Key Features of a Good Intraday Stock

High liquidity: large daily volume so orders fill close to the expected price.
Reasonable volatility: enough movement, measured by ATR, to justify the trade after costs.
Tight price gap: keeps the hidden cost of entering and exiting low.
Presence in the F&O list, off the ban list: usually means deeper order books and more predictable fills.
A genuine catalyst: a reason behind today’s move, rather than random noise.
Sector alignment: moves in step with its sector or the broader index, rather than against it without reason.

Advantages of Careful Stock Selection

Cleaner fills: liquid stocks let you enter and exit close to your intended price.
Lower hidden costs: a tight price gap means less is lost simply by placing the trade.
More predictable stop losses: once volatility is measured, exits behave closer to expectation.
Fewer impulsive picks: a repeatable checklist reduces trading a stock just because it is trending on a channel or a group chat.

Risks and Limitations

Leverage risk: margin magnifies both gains and losses, so a small adverse move can cost more than expected.
Sudden liquidity loss: a normally liquid stock can turn thin during sharp market stress, widening the price gap right when an exit is needed.
Behavioural risk: overtrading and revenge trading after a loss cause more damage than a wrong stock pick usually does.
Auto square-off charges: forgetting to close a position manually often adds an extra fee when the broker closes it for you.
F&O ban volatility: stocks under a position limit ban can see erratic price action and wider gaps until the ban lifts.

Tips for Beginners

Track three to five stocks daily instead of jumping between unfamiliar names each morning.
Place the stop loss order at the same time as the entry order, not afterward.
Trade the first hour and the last hour of the session, and treat the flatter midday stretch with more caution.
Size positions as a fixed percentage of capital, not by how confident a trade feels.
Check the NSE F&O ban list and pre-open heatmap before finalising the day’s watchlist.
Keep a trading journal, noting entry price, exit price, reason for the trade, and outcome, and review it every evening.
Paper trade, meaning practice with no real money, for a few weeks before switching to live capital.

Intraday Trading Compared to Delivery Trading

Intraday Trading:

Time horizon: closes the same day, by 3:30 PM
Ownership: no shares reach the demat account
Capital needed: lower, due to margin
Risk level: higher, due to leverage
Tax treatment: speculative business income, taxed at slab rate
Best suited for: active traders with time through the day

Delivery Trading:

Time horizon: held for days, months, or years
Ownership: shares credited to demat account on T plus one day
Capital needed: full amount paid upfront
Risk level: lower, more time to recover
Tax treatment: capital gains, with separate short-term and long-term rates
Best suited for: long-term investors

Common Mistakes to Avoid

Chasing a stock trending on social media. By the time it is visible everywhere, much of the move is often already priced in, and the price gap tends to widen as volatility spikes.
Picking a stock for its low price alone. A 20 rupee stock with thin volume can be harder to exit than a 2,000 rupee stock with deep liquidity.
Trading through the choppy midday stretch out of boredom. The flattest part of the session is where beginners often force trades that were not really there.
Ignoring brokerage, STT, and GST. On a stock with a small daily range, these can absorb most of the expected profit.
Averaging into a losing position. Adding shares to lower the average price turns a controlled trade into an uncontrolled one, especially with leverage involved.
Skipping a written plan and a journal. Deciding entry, stop loss, and target only after the trade is open invites emotional decisions, and without a journal, the same mistakes repeat unnoticed.

Who Should Use These Golden Rules

These rules suit active traders who can watch the market through the session, roughly 9:15 AM to 3:30 PM, and who are comfortable with margin and tighter risk control. Someone opening a separate demat and trading account specifically for short-term trades, apart from a long-term portfolio, usually finds this approach easier to manage without mixing the two goals.

These rules are less suited to someone who cannot track the market during the day, has low tolerance for quick losses, or wants to build wealth gradually. Delivery-based investing or a systematic investment plan tends to fit that goal better.

Conclusion

Picking the right stock for intraday trading comes down to a handful of checks. Liquidity, traded value, ATR-based volatility, a tight price gap, a genuine catalyst, and staying off the F&O ban list all matter, combined with trading during the hours when moves are actually cleaner. SEBI’s own data shows most retail traders in derivatives lose money, which is a reminder that stock selection is only one part of the picture. Costs, taxes, timing, and a fixed risk per trade rule matter just as much. Get the filtering process right, track your actual costs and outcomes in a journal, and treat each trade as one data point in a repeatable process rather than a one-time bet.
