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.
Pick a famous strategy — Golden Cross, RSI 30/70, MACD, Bollinger reversion, Stochastic — and see what it actually did on your chart after fees, vs. simply holding.
Picks the OHLC source with the cleanest Efficiency Ratio each bar and scales the ATR trailing multiplier to a volatility percentile rank — no fixed source, no fixed band width.
Splits your chart into train/test windows and shows whether a classic strategy's edge survives data it never saw — the same 60/40 mechanic we grade with, free on your chart.
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 $1M+ order-book walls on BTC/ETH perps from our own L2 collector — and whether they get eaten by real trades or pulled before price arrives.
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.
