About position size
Most position sizing is done backwards — a size is picked first and the stop is hoped to hold. The arithmetic runs the other way: the percentage of the account at risk and the distance to the stop together determine the size. A 1% risk with a 5% stop means a position worth 20% of the account; the same 1% risk with a 1% stop means the whole account. The leverage figure here is an output, not an input, which is the point.
Common questions
How do I size a crypto trade from risk?
Decide how much of your bankroll you are willing to lose if the stop hits, then divide that risk by the distance from entry to stop. This page does that arithmetic so size comes from risk rather than from a round-number urge.
What is the 1% rule?
A common heuristic of risking about one percent of equity on a single idea. It is a naming convention people search for, not advice from this site — the calculator accepts whatever risk fraction you type and shows the resulting size.
Does position size include fees and funding?
The basic size-from-stop model here does not simulate funding or taker fees. Those change realised risk after you are in the trade; fold them into your risk budget when they are large relative to the stop distance.
