FAQ

Everything the quants
keep asking.

Data

We aggregate from multiple feeds and consolidate into a single cleansed stream — the same way CFD brokerages construct the data feeds they serve to clients.

Every dataset is verified against multiple sources and passed through a cleansing pipeline that removes outliers, gaps, and stale ticks before it ever reaches MT5.

Data is delivered in UTC+2 (US-DST) to match the NY close — aligned with almost every MT4/MT5 server and guaranteeing exactly 5 daily bars per week.

The spread at bar open. The execution you'd have encountered live is what your backtest sees — no smoothing, no averaging.

Raw tick data is passed through outlier detection, gap reconciliation against secondary feeds, and close-to-open continuity checks before publication.

Plans & access

Full EURUSD history (2003 → today) at minute resolution — enough to evaluate both the data quality and the EA download workflow before upgrading.

Yes. No depth restrictions tied to your start date. The only limit is your plan's generous monthly bandwidth.
