Intraday Risk Management: Stop-Loss, Position Sizing and Risk-Reward
How much to risk per trade, how to size a position from the stop-loss, where to place stops, what risk-reward to aim for and the mistakes that drain accounts.
Short answer
Intraday risk management comes down to four rules: risk only about 1% of capital per trade, size the position from the stop-loss, take trades where the target is clearly bigger than the risk, and stop for the day after a fixed loss.
01Why intraday traders need strict risk rules
Intraday prices can move sharply within minutes, and intraday margin lets you take positions larger than your cash. Both make small mistakes expensive.
A SEBI study published in September 2024 found that 93% of individual traders in equity futures and options made losses between FY22 and FY24. The numbers show why a clear risk plan matters before the first trade.
02The 1% rule and position sizing
Decide the most you will lose on one trade, usually about 1% of trading capital. Then let the stop-loss decide the quantity, not the other way round.
Two stocks with the same ₹2,000 risk can need very different quantities. A stock with a ₹5 stop needs 400 shares; one with a ₹20 stop needs 100. The rupee risk stays the same, and that is what keeps your results steady.

03Stop-loss: types and where to place it
| Type | How it works | Best for |
|---|---|---|
| Level-based | Just below support for a buy, just above resistance for a sell, with a small buffer. | Most intraday setups |
| Volatility-based (ATR) | A multiple of the average true range away from entry, so normal noise does not hit it. | Volatile stocks |
| Fixed percentage | A set percentage from entry, such as 0.5% to 1%. | Simple rule for beginners |
| Time-based | Exit if the trade has not moved as expected within a set time. | Breakout trades that stall |
| Trailing | Moves with price in your favour, never against it. | Locking in part of a move |
Place the stop where the trade idea is proven wrong, not where the loss “feels” comfortable. Avoid round numbers where many stops cluster.
Use a stop-loss (SL) order as soon as the entry fills, or a cover or bracket order if your broker offers one. Never move the stop further away once the trade is live.
04Risk-reward ratio: meaning and formula
The risk-reward ratio compares what you can lose with what you aim to gain. Risk = entry − stop-loss. Reward = target − entry. A trade with ₹10 risk and ₹20 reward has a risk-reward of 1:2.
A good ratio does not make a trade good on its own. The target must be realistic for the stock’s normal daily range and the next resistance or support.
05A complete example: one trade planned end to end
| Capital | ₹2,00,000 |
| Risk per trade | 1% = ₹2,000 |
| Entry | Buy above ₹750 |
| Stop-loss | ₹740 (below the morning low) |
| Quantity | ₹2,000 ÷ ₹10 = 200 shares |
| Target 1 / Target 2 | ₹765 / ₹770 (1:1.5 and 1:2) |
| If the stop-loss is hit | About −₹2,000 plus charges |
| If both targets are reached (half at each) | About +₹3,500 minus charges |
Hypothetical numbers, shown only to explain the process. After Target 1, many traders move the stop-loss to the entry price so the rest of the position carries less risk.
06Daily loss limit and number of trades
Set a daily loss limit, for example 2% to 3% of capital, or three losing trades in a row. When you hit it, stop trading for the day.
Also cap the number of trades. More trades mean more charges and more emotional decisions.
07Leverage and intraday margin risk
Brokers allow intraday positions larger than your cash through margin. Margin does not change how much you should risk; it only changes how large a position you can take. Size every trade on your own capital and the 1% rule.
08Event and expiry-day risk
Quarterly results, RBI policy, the Union Budget and big global events can move prices sharply in seconds. Stop-losses can slip in such moves.
Index option expiry days also bring fast swings in Nifty and Bank Nifty. Trade smaller, or wait, when a big event is due.

10Risk checklist before every trade
- Is the stop-loss level decided and placed?
- Is the quantity worked out from the stop-loss, within 1% of capital?
- Is the target at least 1.5 times the risk?
- Is today’s loss limit still intact?
- Is there a result, policy or expiry event today?
- Is the stock liquid enough to exit at the stop?
- Will I square off before the broker’s cut-off?

?Intraday risk management: FAQs
What is a stop-loss in intraday trading?
A stop-loss is a pre-decided price at which you exit a losing trade. In intraday trading it is usually placed as a stop-loss order right after the entry is filled, so the loss stays within your plan.
How do I set a stop-loss in intraday trading?
Place it just beyond the level that proves your idea wrong, such as below support for a buy. Then work out the quantity so that the loss at that stop is about 1% of your capital.
What is a good risk-reward ratio for intraday trading?
Many traders look for at least 1:1.5 or 1:2. At 1:2 you need to be right only about one trade in three to break even before charges.
How much should I risk per trade?
A common rule is 1% of trading capital per trade, and not more than 2%. Beginners often start lower.
What is the 1% rule in trading?
It means the loss on any single trade, if the stop-loss is hit, should not be more than 1% of your trading capital.
How do I manage risk in option trading?
When buying options, size the position by the premium you can afford to lose and set your exit on the underlying Nifty or stock level. Selling options without enough margin and experience can create large losses.
What is a daily loss limit?
A fixed amount, such as 2% to 3% of capital, after which you stop trading for the day. It prevents one bad day from damaging the account.

No. Risk management cannot guarantee profits. It keeps each loss small and planned, so that one bad trade or one bad day does not wipe out your capital.
