Crypto data is a mess of inconsistent column names, symbol formats, and venue quirks. The dataset catalog maps a clean logical name — 'ohlcv', 'funding' — to a physical table plus a column map and point-in-time semantics, so a strategy says what it n...

An LLM that writes trading code from a one-line description is a parlor trick — unless it's grounded in the exact authoring API, the live dataset catalog, and real sample rows, and its output is validated against the same sandbox the engine uses, wit...

A strategy editor whose autocomplete drifts from the engine is worse than no autocomplete — it confidently suggests methods that don't exist. Ours introspects the real source on every request, so the surface you're offered is exactly the surface that...

A platform that lets users write Python and run it on your infrastructure has a hard problem: that Python could try to escape. Here's the layered sandbox — save-time AST validation, restricted builtins, an allowlisted importer — that lets quants writ...

A profitable strategy is half a fund. The other half is investor accounting that doesn't drift: unitized NAV-per-unit, pro-rata P&L, management and performance fees with a high-water mark, and a compliance-grade execution audit trail. Here's the acco...

Research velocity is a competitive edge. A grid of five parameters across five values is 3,125 backtests — and on our engine the data for all of them is pulled once, cached as parquet, and reused. Here's how the sweep harness and the cache turn a cof...

The deadliest gap in systematic trading is between the code you backtested and the code that trades live. We close it by running the exact same engine in both — preflight in milliseconds, backtest in minutes, then schedule the identical strategy as a...

If your backtester ignores funding, every carry, basis, and delta-neutral strategy you test is a fiction. Our engine accrues funding per bar on live mark notional, prorated by each venue's own funding interval — so a Binance 8h feed and a Hyperliquid...

Most backtests quietly leak the future into the past. Here's how our engine makes look-ahead bias structurally impossible — as-of joins on the bar clock, per-instrument freshness TTLs, and a leak-check attestation on every preview....
