The whole platform is visible from every tier — locked things open and explain themselves. What a plan carries is depth: how much you can compute, how far you can validate, and whether a study can be published.
Build real strategies and run them on real market history. No card.
An account, an email address, nothing else
Locked features still open and explain themselves. You can see the whole platform before you pay for any of it.
The whole working platform — validate properly, then trade it forward on paper.
Everything in Free, plus
Everything, and the instrument that publishes: sealed studies you can defend.
Everything in Practitioner, plus

| Build and run your own circuits | Yes, with the Free cards, on a ticker, a basket or the NASDAQ-100 | Every card but the Research ones, on every index | Every card |
| A published study's own circuit, its settings changed | 3 runs a day | No daily count | No daily count |
| Save circuits as projects, with their history | Yes | Yes | Yes |
| Register a run before you score it | Yes | Yes | Yes |
| Factor cards, routers and paper-trade cards | Only in a published study's circuit | Only in a published study's circuit | Yes |
| Walk, write up and publish a research study | No | No | Yes |
| Paper-trade a whole circuit, 30 to 90 days, marked each evening | No | No | Yes |
| The platform's modules | |||
| The Universal Builder, and the four strategy families’ Overlay and Builder | Yes, on daily bars | Yes, and on 1 to 6 hour bars | Yes, and on 1 to 6 hour bars |
| Walk-forward, scanners, stochastic methods, regime analysis and its optimiser, the portfolio backtester, the fundamentals | No | Yes | Yes |
| Factor models and the Portfolio Visualizer | No | No | Yes |
| Paper trading in the Basic, Advanced and Stochastic lanes, marked once a day after the US close | No | 10 per lane | 20 per lane |
| Standalone Python export | The Universal Builder's, on daily bars | Backtests, walk-forwards and grid searches | Backtests, walk-forwards and grid searches |
| Time Travel: each date sees only what was knowable then | Yes | Yes | Yes |
| In ChatGPT and Claude | |||
| Read the studies, the catalogs and your saved work | Yes | Yes | Yes |
| Runs: backtests, walk-forwards, scans, stochastic methods, regime analysis and your saved lab circuits | 3 a day in all | Each kind up to its daily cap: 50 backtests, 50 stochastic-method backtests, 10 walk-forwards, 10 lab circuits, 30 mean-reversion scans, 15 pairs scans, 20 regime analyses, 10 regime optimisations | The same caps, and lab circuits with Research cards |
| On every plan: 3 runs at once, on daily bars, and a refused call does not count. A lab circuit run from an assistant needs Research only for its Research cards (the factor models, the routers, paper-trade markers). | |||
What does the free tier actually do?
It builds. You get the Overlay and Builder for all four strategy families, the Universal Builder on daily bars, and the lab with a working set of cards — a ticker or a basket or the NASDAQ 100, six screens, a signal and a forward test, and the Discretionary engine in full. You can run those circuits on real market history, save your work, and register what you found, and a published study’s own circuit runs three times a day with its settings changed. In ChatGPT or Claude it runs three a day of anything an assistant can start, walk-forwards and regime analysis included. What free does not include is paper trading, and in the platform’s own modules walk-forward, optimisation and regimes.
Which plan should I pick?
Start free — it is a real tier, not a demo, and you will know within an afternoon whether this is your kind of tool. Practitioner is where most people work: walk-forward validation, regimes, stochastic methods, the fundamentals desk, and paper trading in every lane. Take Research when you want to run sealed studies and publish them, paper-trade a whole circuit, or use the factor models and routers.
Can I move between plans?
Yes, in both directions. Your saved configurations, backtests, projects and registered hypotheses stay with your account either way — moving down pauses what a plan carries, it never deletes your work.
Do you offer plans for firms and institutions?
Yes, under a licence agreed in writing, per seat and invoiced. The plans on this page are for personal use. Write to contact@quanterlab.com with the number of seats and what the team does, and you get an offer.
What markets are supported?
Equities and indexes. For the US indexes the membership is point-in-time and the fundamentals come with it — every date sees the constituents and the filings that were knowable then, which is what makes a backtest over them worth reading.
Can I export my strategies?
Yes. The Universal Strategy Builder exports standalone Python files you can audit and run on your own, on every plan (daily bars on Free); the walk-forward’s and the grid searches’ exports come with Practitioner. No black box.
Is there live brokerage integration?
No. QuanterLab is a research platform and does not connect to a broker or place orders. Paper trading marks your strategy forward against real market data, with no money involved.
