Real market data, every asset class.
Flip Live market data in the builder and a strategy runs on real, point-in-time OHLCV, no look-ahead, realistic costs. Below is exactly what's wired today and what's next, by asset class and by data kind. We mark tick and order-book honestly: free where it exists, paid-only or non-existent where it doesn't, no vague “soon”.
Coverage by asset class
Each class shows the three data kinds the engine can consume: candlesticks, raw tick, and Level-2 depth.
Crypto
Spot majors, 24/7. The deepest free history of any asset class here.
Full history to listing, 1m–1D, no API key. Wired.
Free aggTrades/trades ZIP dumps (data.binance.vision); tick ingestion is the next step.
The only free historical order-book depth anywhere (Bybit orderbook.500, Binance-futures bookDepth) + live WS.
Stocks
US single-name equities, also the underlyings for single-stock CFDs.
Intraday (5m ≤ 60d, 1h ≤ 730d) + daily back to the 1980s. Wired.
Free IEX trades/quotes via REST (15-min delayed, ~2.5% of volume). Consolidated SIP tick is paid.
Consolidated equity depth (TotalView, MBO) is paid-only; Databento gives a $125 free credit for samples.
ETFs
Index and sector ETFs, the most liquid retail proxies for the indices.
Same coverage as equities: intraday + decades of daily. Wired.
Free IEX feed, 15-min delayed; SIP tick paid.
Order-book depth via paid vendors only.
Index & equity futures
CME E-minis, the contracts behind most index CFDs.
Front-month continuous (=F), intraday + daily. Note: not roll-adjusted. Wired.
Real CME tick/MBO is paid (Databento $125 credit for samples). No free historical futures tick.
CME order-book (MBP-10/MBO) via paid vendors only.
Forex
Spot FX majors, 24/5. Retail 'forex' is itself a rolling-spot CFD product.
Spot majors (=X), intraday + daily. Wired.
Free historical tick (bid/ask) back to ~2003 via the Dukascopy datafeed; ingestion pending.
No public order book. Traded over-the-counter, so consolidated depth doesn't exist.
Metals
Gold & silver, as COMEX futures and as spot/CFD (XAU/XAG).
Futures (GC=F/SI=F) and spot (XAUUSD=X/XAGUSD=X). Wired.
Free spot-metal tick (XAU/XAG) via Dukascopy, the only free tick source for metals.
No public order book. Traded over-the-counter, so consolidated depth doesn't exist.
Indices
Cash indices, the reference for index CFDs and futures.
Cash indices (^GSPC/^NDX/^DJI/^RUT/^VIX), intraday + daily. Wired.
Index-CFD tick proxy (broker quotes) via Dukascopy.
A cash index has no order book of its own (its constituents/futures do).
Energy & commodities
Crude, natural gas, and base/other metals futures.
WTI/Brent/NatGas/copper/platinum futures (=F). Wired.
Exchange tick is paid; Dukascopy covers some as CFDs.
Exchange depth via paid vendors only.
CFDs
A CFD tracks an underlying, so it runs on the underlying's data, with spread & financing modelled as costs.
Index/metal/energy/stock CFDs map to ^GSPC/ES=F, XAUUSD=X, CL=F, the stock ticker, etc.
Dukascopy is itself a CFD broker: free CFD tick for FX/metals/indices.
No public order book. Traded over-the-counter, so consolidated depth doesn't exist.

All backtests are hypothetical / simulated results (CFTC Rule 4.41(b)). Market data is fetched from public endpoints for research and education only. It is delayed/best-effort, not redistributed, and is not investment advice. Futures OHLCV is front-month continuous (not roll-adjusted); CFDs are modelled on their underlying with spread & financing applied as costs. Every provider sits behind one swappable adapter, so moving to a licensed vendor at scale is a one-file change.
