AXOQUANT

Coverage

Twenty-one exchanges, four asset classes, minute bars to daily.

Enforced relationships are individually small. A share-class pair, a geared fund's rebalance mandate, a defended currency band — each is real, and each has a capacity ceiling measured in single-digit millions. A book built on them only works if you can find many, across many venues.

So breadth is not ambition here, it is arithmetic. We hold one-minute bars wherever the venue publishes them — crypto, US equities, foreign exchange — and daily bars across the full international catalogue, resampled to every horizon in between. Refreshed nightly, and kept as raw vendor files we never delete, so any figure on this site can be recomputed from source.

What we can trade, and what we only study

Coverage and access are different things, and conflating them is how research becomes untradeable. Every market above is priced through a venue-specific cost model — commissions, exchange fees, transaction taxes, borrow, and the currency leg — before any result is believed.

Access status, and the constraints that shape what is testable.
MarketStatus
Europe, UK, US, Canada, Australia, Singapore, FX, US options, volatility futures Tradeable. Transaction taxes decide which mechanics survive — a half-percent stamp duty on purchases rules out anything with weekly turnover, and the honest answer is to design around it rather than ignore it.
Mainland China Tradeable long-only, with next-day settlement and daily price limits. A limit-locked session is modelled as no fill, not as a fill at the limit.
Crypto Sandbox execution against live market data, on the production code path. Real-money access is pending a regulatory restriction outside our control.

Where we looked and found nothing

A coverage list that only shows productive markets is a selection-bias exhibit. US equities is the clearest negative result we hold: a full campaign across the liquid universe — cointegration and tracking families, cross-sectional momentum and mean reversion, breakout, share-class pairs — with matched control ensembles per candidate, produced no book that passed both the survivability and specificity gates at real per-share costs.

The planted control in that campaign was correctly refused, which is the reading that matters: the instrument returned a zero where a zero was the truth. Statistical relationships in the most efficient equity market on earth are, on our evidence, indistinguishable from chance once costs and controls are applied. We publish that, and it is why the search moved to relationships something is obliged to maintain.
