The 1% rule is not about how much you invest — it is about how much you are willing to lose on a single trade. Limiting your loss per trade to 1% of your capital means you need 100 consecutive losing trades to lose everything. In practice, no consistent trader ever hits that. The 1% rule is the foundation of trading survival.
What Is the 1% Rule?
The 1% rule states that you should never risk more than 1% of your total trading capital on any single trade. "Risk" here means the maximum amount you can lose on the trade — the distance from your entry to your stop loss, multiplied by your position size.
Risk per trade = Entry price − Stop loss price × Number of shares/lots
This is not the same as "invest only 1% of your capital." You can invest ₹50,000 on a trade while risking only ₹2,000 (1% of a ₹2,00,000 account) — as long as your stop loss is set at the level where the loss equals ₹2,000.
Why 1%? The Mathematics of Survival
The 1% rule is not arbitrary. Here is the math that makes it the professional standard:
- With 1% risk: Even after 20 consecutive losing trades (extremely unlikely), your account is down only 18.2% (compounding effect). You still have 81.8% of your capital and can recover.
- With 5% risk: After 20 consecutive losses (common during bad streaks), your account is down 64.2%. Recovery from this is extremely difficult psychologically and mathematically.
- With 10% risk: After 10 consecutive losses, your account is down 65%. After 20, essentially wiped out. This is how most Indian retail traders blow their accounts.
Even the best traders in the world have losing streaks of 5–10 trades. The 1% rule ensures that a losing streak damages your account but never destroys it. The goal is to survive long enough for your edge to play out over hundreds of trades.
The Position Sizing Formula for Indian Traders
Use this formula before every trade:
Stop Distance (points) = Entry Price − Stop Loss Price
Position Size (shares) = Risk Amount ÷ Stop Distance
Position Size (Nifty lots) = Risk Amount ÷ (Stop Distance × 75)
Worked Examples — Indian Account Sizes
| Account Size | 1% Risk (₹) | Stop Distance | Nifty Lots | NSE Stock Shares |
|---|---|---|---|---|
| ₹50,000 | ₹500 | 50 pts | 0.13 (not tradeable — skip or paper trade) | 10 shares of ₹50/stop stock |
| ₹1,00,000 | ₹1,000 | 50 pts | 0.27 (minimum 1 lot — 2.7% risk) | 20 shares |
| ₹2,00,000 | ₹2,000 | 50 pts | 0.53 (1 lot = 1.87% risk — close enough) | 40 shares |
| ₹5,00,000 | ₹5,000 | 50 pts | 1.33 lots (use 1 lot — 1% risk) | 100 shares |
| ₹10,00,000 | ₹10,000 | 50 pts | 2.67 lots (use 2 lots — 1% risk) | 200 shares |
| ₹25,00,000 | ₹25,000 | 50 pts | 6.67 lots (use 6–7 lots) | 500 shares |
Nifty futures and options require trading in lots of 75. One lot at a 50-point stop = ₹3,750 risk. For a ₹1,00,000 account, this is 3.75% risk per trade — nearly 4× the recommended limit. If your account is below ₹3,00,000–₹4,00,000, you cannot trade Nifty F&O at 1% risk per trade. In this case: (1) Trade NSE stocks with smaller lot sizes, (2) Paper trade until you build the account, or (3) Accept 2% risk maximum — but never more. Blowing a small account on Nifty F&O with oversized positions is the most common way Indian retail traders lose money.
Adjusting Position Size for India VIX
The 1% rule gives you your maximum position size. India VIX tells you when to use less than the maximum:
- VIX below 15: Use full 1% risk per trade.
- VIX 15–20: Use 0.75% risk per trade.
- VIX 20–25: Use 0.5% risk per trade.
- VIX above 25: Use 0.25% risk per trade or skip intraday trading.
The Daily Loss Limit — Your Second Layer of Protection
Even with 1% risk per trade, a series of losses in one session can be psychologically devastating and lead to revenge trading. Add a daily loss limit:
- Daily loss limit = 2–3% of account capital. If you lose 2% of your account in one day, stop trading for the rest of the session. No exceptions.
- For a ₹2,00,000 account: Daily limit = ₹4,000–₹6,000. Once you hit this, close your charts and step away.
- Write the daily loss limit in your trade journal every morning. Commit to it before the market opens — not after you've already lost ₹3,000 and are tempted to "get it back."
Account: ₹3,00,000. VIX: 14.5 (normal). 1% risk = ₹3,000.
Trade setup: Nifty bullish pin bar at PDL (24,050). Entry: 24,080. Stop: 24,010. Stop distance: 70 points.
Position sizing: ₹3,000 ÷ (70 × 75) = ₹3,000 ÷ ₹5,250 = 0.57 lots → round to 1 lot.
Actual risk with 1 lot: 70 × 75 = ₹5,250 = 1.75% of account.
Decision: 1.75% is above 1% but below 2%. Given clean setup and normal VIX, acceptable to proceed with 1 lot. If VIX were above 18, would skip or use a stock trade instead.
Target: 24,280 (PDH). Reward: 200 points × 75 = ₹15,000. R:R: ₹15,000 ÷ ₹5,250 = 1:2.86. Acceptable.
Before your next trade, calculate your exact risk in rupees. Write it down: "I am risking ₹X on this trade." Then check: is ₹X less than 1% of your account? If yes, proceed. If not, reduce your position size until it is. This discipline, practised on every single trade, is what separates traders who survive from traders who don't.
