❓ Frequently Asked Questions

1. Why is position sizing important in forex?

Proper position sizing protects your capital from large losses. Even with a 50% win rate, poor lot sizes can wipe out an account. This tool ensures you never risk more than you plan.

2. How is the lot size calculated?

Formula: Lots = (Account Balance × Risk%) / (Stop Loss in pips × Pip Value per Lot). The calculator does this instantly.

3. What is a pip value and why does it change?

A pip is the smallest price move. Pip value depends on the currency pair. For USD pairs, 1 standard lot = ~$10 per pip. Our tool auto-adjusts or you can enter a custom pip value.

4. Can I use this for crypto or gold trading?

Yes. Enter a custom pip value (e.g., gold: 1 pip = $1 per ounce) and your stop loss in points. The same risk formula works perfectly.

5. What if my broker uses different lot sizes?

Standard lot = 100,000 units. Mini = 10,000, Micro = 1,000. The calculator shows all three, so you can adapt to any broker.

6. How accurate is the pip value for exotic pairs?

For major pairs it is very accurate. For exotics, simply enter the pip value manually (ask your broker). The calculator then uses your exact number.

7. Should I round the lot size down or up?

Always round down to be safer. Use mini or micro lots for better risk control.
