Sydney Quant Pty Ltd · Australia
An independent research studio. We run our own trading infrastructure, build market analytics, and ship consumer software — the model, the backend, the app and the store listing, all under one roof. Five of our tools run live on this page.
Trading & markets
Six stages, one system. What the models look for is ours; how the thing is engineered and operated is the part worth publishing — and the part that decides whether a strategy survives contact with a live venue.
Data is captured continuously and stored raw, before any cleaning, so a decision made last month can be re-examined against exactly what the system saw at the time rather than a tidied-up version of it.
Research and production run the same code. A backtest is the live engine fed historical data through the same interface, so a result in research is the result you get in production — not a cousin of it.
Models are evaluated on a schedule against current data, and every output is stamped with the inputs and the version that produced it. A signal that cannot be traced back to its inputs is not allowed to size a position.
Orders are sized from the model's conviction and the account's risk budget, then routed with idempotency keys so a retry after a timeout can never become a second position.
Limits on position, exposure, order rate and drawdown are checked before submission, not after the fact. Positions reconcile against the venue on every start, every reconnect and on a schedule between — a mismatch halts trading rather than being netted away.
Every session writes a log detailed enough to reconstruct it tick for tick. When something odd happens it gets replayed, not argued about. Alerting is tuned for the things that actually matter — gaps, rejects, drift, and silence where there should be traffic.

Flagship app
The studio’s consumer flagship, and the clearest proof that the whole stack works: model, backend, client, store listing and support, all in-house. Free on the App Store right now.
Two players get the same questions at the same time, and it is settled on speed and accuracy. Points come from answering fast and from stringing correct answers together, so a clean run beats a careful one — which is what makes the last ten seconds worth staying for.
Ratings move on results, matchmaking pairs you against players near your level, and the leaderboard resets weekly so a good week actually counts. Play as a guest with no account at all, or sign in so a rating follows you between devices.
No ads, no advertising identifiers, no data sales. The app collects what matchmaking and rankings need and nothing beyond it — the privacy policy spells out every field, and deleting your account takes one email.
The lab
The audio visualiser is a browser port of the studio’s offline renderer — same layer model, same colormap. The tax tool runs the same bracket schedule as the shipped app. Both are yours to drive.

How we work
Not aspirations on a wall. These are the review criteria every commit in every repository gets held against.
Code is read far more than it is written, and debugged at the worst possible moment. Boring, obvious implementations beat elegant ones that need a mental run-up.
Any number a system produces should be traceable to the inputs that made it. If a result cannot be explained in plain language, it does not ship.
Anything touching money stops rather than guesses. Stale data, a lost connection or a breached limit halts the system; nothing resumes without reconciliation.
Model, backend, client and store listing. Owning every layer means the second product costs a fraction of the first, and no vendor gets to decide the roadmap.
The studio
Sydney Quant is an Australian private company that designs, builds, ships and operates everything on this site. Research, engineering, design, release management and support all happen in the same place.
Everything here is made by cheesepickle. That is the only name attached to it, and it is the one to use if you write to us. There are no headshots, no bios and no founder story — the catalogue is the whole pitch, and it either holds up or it doesn’t.
Not everything survives. Three apps in the catalogue were built, released and later taken down, and they are labelled that way rather than quietly left looking live. The two that are still on the App Store are linked directly.
Trading work is discussed at the level of systems, infrastructure and risk. Strategies, signals, instruments and parameters are not published, here or anywhere, and no amount of asking nicely will change that.
