The 2% rule: Risk no more than 2% of your account per trade. On ₹1 lakh, that is ₹2,000 max loss per trade. This keeps you in the game long enough to develop skill. Most traders who blow accounts are risking 20–40% per trade without realising it. Practice sizing trades correctly on PaperPe before real money is involved.
