Data and limits

What the platform runs on, what it lets out, and the allowances that keep one account from crowding out the rest.

Where the data comes from

Prices, financial statements, index membership and the screener universe come from Financial Modeling Prep under a commercial licence. Daily bars everywhere; intraday bars from five minutes to four hours in the Universal Builder on Practitioner and above. Statements are kept as first published, and a restatement stays in its own epoch, so a run pinned to 2009 reads the 2009 filing.

Constituent lists are point-in-time. A name that later left an index is in the windows where it belonged, and a name that joined later is absent from the windows before it joined. Price history for names that have since left the market is thinner than for the survivors, and a study on a universe says so in its limits.

Redistribution

What leaves the platform

On the site
Charts, reports and papers, as the platform shows them to you.
Exported code
A strategy exported as standalone Python, on Practitioner and above, carries the logic. It fetches its own data when you run it; none of ours ships inside it.
Through an assistant
The hosted connector and the desktop's local server return results: metrics, scanner outputs, your saved work, the published papers. Never a price series, never raw fundamentals. The desktop fetches bars through the platform under your sign-in, keeps them for the engine on your machine, and gives none of them to the assistant.
Bulk
There is no download of price or fundamental data, on any plan. The vendor licence does not allow it and the terms say the same.

Allowances

Limits by surface

SurfaceAllowanceWhen it is reached
Paper trading10 slots in each of the three lanes on Practitioner, 20 on Research.Close a paper trade to open another.
The hosted connector5,000 reads a day, 200 catalog calls a day, 200 saves a day, and 3 tasks in flight at once, per account.The tool answers with the limit and the time it resets; nothing is queued.
The desktop's data proxy5,000 data calls a day per account, shared by everything the engine on your machine fetches.The engine reports the limit; a run that needs more data waits for the next day.

The allowances are set so that a person working a full day does not meet them, and a script does. If your work does, write to contact@quanterlab.com and say what it is.
