TILLAHistorical data that refills itself
Go offline for an hour or a week: one call brings back every bar you missed, and a second brings every value a source corrected later.
Most market-data APIs give you history and leave the rest to you: notice the gap, work out what is missing, re-download it, and hope nothing was revised in the meantime. TILLA builds the recovery into the API.
The three calls
- Tick —
GET /v1/<tier>/tick: every series your plan holds for the bar that just closed, in one answer. - Resume —
GET /v1/<tier>/resume/<layer>/<lane>?since=...: every bar since you stopped, streamed in one request (JSON lines, CSV or Parquet). - Changes —
GET /v1/<tier>/changes?since=...: every value corrected since a time, with its value now. Apply them and your copy matches ours.
The free starter package does all three in one command and keeps a SQLite file current:
python tilla_dashboard.py --keep tilla.db.
How far back
- Hourly history for crypto from 2017 and for FX from 2002 (
/v1/<tier>/deep/hour). - Every clock from 1-minute to quarterly for the live set: crypto spot and derivatives, US stocks and ETFs, FX, rates, macro and our own Bitcoin node.
- Each plan's window: Free 30 days, Builder 6 months, Pro 1.5 years, Max the whole set (pricing).
Why the values can be trusted
Every bar is labelled by its close, in UTC. A value a source never published stays empty; nothing is filled in or guessed. The 293,743 derived indicators are computed bar by bar from the raw values with no look-ahead, so a backtest sees only what was known at the time.
FAQ
How do I fill gaps after my bot was offline?
Call /v1/{tier}/resume/{layer}/{lane}?since= with the time of your last bar. It returns every bar since then in one streamed request.
What happens when an exchange corrects a number?
The corrected value appears in /v1/{tier}/changes. Apply those rows and your local copy matches the source again.
How far back does the history go?
Hourly crypto from 2017 and FX from 2002; each plan reaches back a set window - Free 30 days, Builder 6 months, Pro 1.5 years, Max the whole set.
Is there look-ahead in the indicators?
No. Every indicator is computed bar by bar from values that existed at that bar.
