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.
All three market clocks in your browser side panel, plus a live 4H-close countdown on the toolbar icon. Free, no account, zero network requests.
Our breakeven win-rate math as a free open-source indicator on your chart: required win rate after costs, expectancy in R, and a one-line verdict.
Live annualized funding across 10 exchanges with the cross-venue spread highlighted — from our own collectors, refreshed every few minutes.
Live timers to the next 5m through monthly candle close, UTC-aligned like Binance and TradingView. The clock closed-candle strategies actually run on.
Next funding payment on every major perp venue, live. Hold through the timestamp and you pay for the whole interval — know exactly when it hits.
Sydney, Tokyo, London, New York and CME crypto futures — what's open now, the overlap, and the daily halt, with DST handled automatically.
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.
