Risk management

Most traders do not fail for lack of good ideas. They fail because one bad day wipes out many good ones.

Risk comes first

SEBI's 2024 study of the equity F&O segment found that about 9 in 10 individual traders lost money over three financial years. The traders who survive long enough to improve almost always follow the same simple rules: small risk per trade, a stop decided in advance, and a record of every trade.

The 1% rule

Risk no more than about 1% of your trading capital on any single trade. "Risk" means the amount you lose if your stop is hit, not the amount you spend.

With ₹2,00,000 of capital, 1% is ₹2,000. Ten losing trades in a row would cost about 10% of your capital: painful, but you are still in the game.

Position sizing, step by step

  1. Decide your stop first, from the chart (for example, just below support).
  2. Work out the loss per lot if that stop is hit.
  3. Divide your 1% budget by that loss per lot, and round down.
Worked exampleCapital ₹2,00,000, so the 1% budget is ₹2,000. You buy a NIFTY call at ₹100 and your stop (NIFTY breaking support) would take the option to about ₹70. Risk per unit ₹30 × 65 units = ₹1,950 per lot. ₹2,000 ÷ ₹1,950 = 1.02, so you trade 1 lot, not the 30 lots your capital could technically buy.

Where to put stops

  • Use the index chart, not a random percentage. Put the stop where your idea is proven wrong: below the support you bought above, or above the resistance you sold below.
  • Leave room for noise. A stop inside normal one-minute wiggles gets hit by randomness. Look at the average range (ATR) before choosing.
  • Convert it to a premium level. Ask what the option would trade at if the index reached your stop. SWOT TRADER's "Use auto levels" button does this for you.
  • Never widen a stop once you are in. Moving it to break-even or trailing it to lock profit is fine.

Reward : risk

Reward : risk compares the planned gain at your target with the planned loss at your stop. A trade risking ₹30 to make ₹60 is 2 : 1. Many traders skip setups below 1.5 : 1, because a strategy that wins half the time still loses money if the winners are smaller than the losers.

Expectancy: are you profitable over 100 trades?

Expectancy per trade = (win rate × average win) − (loss rate × average loss).

Worked exampleYou win 40% of trades with an average win of 2R and lose 60% with an average loss of 1R ("R" is the amount risked). Expectancy = 0.4 × 2 − 0.6 × 1 = +0.2R per trade. At ₹2,000 risked per trade, that is about +₹400 per trade on average, before charges, even though you lose more often than you win.

Charges and STT

Every order costs more than brokerage. From 1 April 2026 the Securities Transaction Tax on option sales rose to 0.15% of the premium, and on futures sales to 0.05%. A typical breakdown for options:

ChargeTypical rate (options)Charged on
Brokerage₹20 per orderCommon discount-broker rate; varies by broker
STT0.15%Premium on the sell side
STT on exercise0.15%Intrinsic value of options settled in the money
Exchange transaction charge≈0.035%Premium, both sides (NSE)
SEBI turnover fee₹10 per crorePremium, both sides
Stamp duty0.003%Premium on the buy side
GST18%On brokerage, exchange and SEBI fees
Worked exampleBuy 1 NIFTY lot at ₹100, sell at ₹120: a ₹1,300 gross profit. Brokerage ₹40, STT about ₹12, exchange fees about ₹5, GST about ₹8, stamp duty under ₹1: roughly ₹65 in total, about 5% of the profit. Scalp for ₹2 a unit instead and the same charges take half your gain.

Rates change with budgets and exchange circulars. SWOT TRADER deducts all of these from every simulated trade so your results are realistic.

Daily habits that protect capital

  • A daily loss limit. Stop trading for the day after losing 2–3% of capital.
  • No averaging down on a losing option. Expiry-day premiums can go to zero.
  • Trade less after a big win. Overconfidence is a risk too.
  • Keep a journal: setup, entry, stop, target, result, and one lesson. SWOT TRADER's end-of-day statistics page is a ready-made journal.
Practise it. Play a day where every trade uses a stop, sized with the 1% rule. The "Risk manager" and "Set a stop on every trade" challenges reward exactly this.
