Free, instant, no signup, no email gate. The same arithmetic we use inside the grading engine, opened up — including the one calculator most sites won't show you: the breakeven curve that explains why most high win-rate strategies make nothing.
Live annualized funding across 10 exchanges with the cross-venue spread highlighted — from our own collectors, refreshed every few minutes.
Size the position from the risk: account, risk %, entry and stop in — exact size, quantity, and the leverage it implies out.
Where the exchange ends your position, long or short, and how little the market has to move to get there.
Turn a per-interval funding rate into annualized APR and the real dollar cost of holding your position.
The win rate your reward:risk actually requires, your expectancy after costs, and which side of the curve you're on.
Calculators answer the arithmetic. Whether the strategy behind the numbers has an edge is a different question — the one we built the grader for.
