How the calculator works
Position sizing starts from the loss, not the profit. You choose the share of the account you accept losing if the trade is wrong, find the price where your thesis fails, and let the distance between entry and stop decide how large the position can be.
- Amount at risk = account size × risk per trade.
- Position size = amount at risk ÷ (entry − stop) for a long, or ÷ (stop − entry) for a short.
- Margin = position value ÷ leverage.
- Estimated liquidation = entry × (1 − 1 ÷ leverage) for a long, entry × (1 + 1 ÷ leverage) for a short.
The rule that keeps leverage from becoming a gamble: your stop must sit well before the liquidation price. Read the full walkthrough in How to Size a Crypto Position Around Your Loss Boundary and Crypto Leverage and Liquidation, Explained.
Questions
Divide the dollars you are willing to lose by the distance from your entry to your stop. Risking $500 with a $3,000 stop distance per coin allows 0.1667 coins. The stop sets the distance; your risk rule sets the dollars.
It should not change your risk. A position sized from the stop loses the same dollars at 2x or 20x. Leverage changes the margin you post and how close the liquidation price sits to your entry.
It uses the common approximation entry × (1 − 1 ÷ leverage) for longs and entry × (1 + 1 ÷ leverage) for shorts. Exchanges add maintenance margin and fees, so the real level arrives a little sooner. Always check the figure your platform shows.
Many disciplined traders keep risk between 0.5% and 2% of the account per position so a losing streak stays survivable. Choose a number before you look at the chart and keep it fixed.
