What is a position size calculator?

Position sizing is the most important number most traders never calculate. It decouples 'how confident am I' from 'how much can I lose', and it's the difference between a drawdown you recover from and one you don't. The risk-first method is simple: pick the fraction of your account you're willing to lose on a trade (say 1%), set where you'll be wrong (the stop), and the position size falls out of the math. Do that on every trade and no single loss — or even a losing streak — can wreck you. A good calculator makes this instant and adds the things leverage traders need: required margin, distance to liquidation, and the reward:risk of a planned take-profit. Cryptohopper.AI generates that exact tool, running entirely in your browser, from one sentence.

Common features

  • Account balance, risk %, entry, and stop → exact position size
  • Reward:risk and R-multiples for a chosen take-profit
  • Leverage support: required margin and liquidation distance
  • Long and short, any pair
  • Runs fully client-side — nothing is transmitted
  • Clean, fast inputs with instant results

Real-world examples

Fixed-fractional risk

Risk exactly 1% of the account per trade; the calculator returns the units to buy given your entry and stop.

Leverage check

See the margin a leveraged position needs and how far your stop sits from liquidation before you place it.

Reward:risk planner

Enter a take-profit and instantly see whether the trade clears your minimum R-multiple.

Why Cryptohopper.AI fits position size calculator projects

It's a calculator you'll actually use — yours, ad-free, on your own subdomain, with every number computed locally. Cryptohopper.AI builds it from a sentence and you can tweak the defaults, add your usual pairs, or fold it into a trading-journal in the same chat.

常见问题

Why size positions by risk?
Risk-first sizing means each trade risks the same fixed fraction of your account, so a string of losers can't blow you up. You set the risk %, the stop distance does the rest — the single highest-impact habit in trading.
Does it handle leverage?
Yes — it can show required margin and how close your stop sits to liquidation, so you size with leverage safely.
Is it accurate?
The math is exact and runs in your browser — nothing is sent anywhere. It's a planning tool, not trading advice.
