How to Calculate Position Size

If you ask a beginner "how much are you risking?", they say "£50." If you ask a pro, they say "1%." This guide teaches you the math of professional risk management.

01

Determine Your Risk Amount

Choose a fixed percentage (e.g., 1%) of your account balance. This is your "Risk at Risk".
02

Use the Position Size Formula

Lot Size = (Account Risk Amount) / (Stop Loss Distance in Pips * Pip Value). This ensures that no matter where your stop is, you only lose 1%.

Common Mistakes to Avoid

  • /Using the same lot size for every trade
  • /Ignoring pip value differences between currency pairs
