Most professionals risk between 0.25% and 1% of their account per trade. Above 2%, a normal losing streak can permanently damage the account.

DEEP DIVE
Understanding Position Size
What is position sizing?
Position sizing is the mathematical process of deciding how many lots to trade so that every setup risks a controlled, pre-agreed portion of your account.
It replaces guessing with a formula: balance × risk% ÷ (stop in pips × pip value per lot). The output is the largest position you can take without breaching your risk rule.
The 1–2% rule
Most professional desks cap risk at 1–2% per trade. On a $10,000 account that is $100–$200 of potential loss, no matter how good the setup looks.
Ten consecutive losses at 2% risk still leave you with over 80% of your capital — plenty of room to recover. Ten losses at 10% risk would close the account.
PRO TIPS
How to use it well
01
Place your stop at a level that actually invalidates the setup first, then let the calculator size the trade to fit — never the other way round.
02
When two open trades share a currency, treat their combined risk as one exposure. USD strength affects EUR/USD and GBP/USD together.
03
Recalculate whenever your balance shifts by more than ~10%. Position size should grow with the account, not with confidence.

FAQ
Position Size Calculator — questions
-
01
What percentage of my account should I risk per trade?
-
02
Why does the calculator ask for entry and stop prices?
It converts the distance between them into pips, then combines pip value with your risk in cash to derive the exact lot size for the pair you’re trading.
-
03
When should I use the custom pip value field?
Only if your broker’s pip value differs from the standard $10 per standard lot on USD-quoted pairs, or for CFDs and indices where you have a fixed value per point.
-
04
Does this work for indices and metals?
Yes. Gold (XAU/USD) is included in the pair list. For custom instruments, enter the cash-per-pip in the custom pip value field.
