How to

How to download DYDXUSDT historical data

  1. Open the Data Shop — the link lands on the most-recorded DYDXUSDT instrument; every other venue and class of the pair is one row of the exchange matrix above, and each row links straight to its own instrument.
  2. Pick a UTC day in the calendar. Each day is one file with every trade, order-book update and quote the venue published — the shop shows the day's candle and file size before you buy.
  3. Try a free sample day first — one complete day of a major pair, same schema, no sign-up.
  4. Check out as a guest — pay by card, no account, no sales call — and the file downloads immediately at €1 per instrument-day. Buying many days? Select them across the calendar or use the scanner bulk-add.
  5. Need CSV or Parquet instead of the native tick file? Append ?format= to any download — see the formats overview for the trades, BBO and liquidation exports.

Why CryptoStruct

Why buy DYDX/USDT data here

Four things every page on this site is built on — and the reason the numbers above exist at all.

We record everything

The complete public feed of each venue as it was published: every Level-2 snapshot and update at the venue's full book depth, every trade with its aggressor side, every quote, funding, mark-price and liquidation event — for every instrument the venue lists, every UTC day since we added the venue. Nothing sampled, no top-N cut, no on-demand capture.

Institutional grade

Captured co-located at the venue with the exchange timestamp and our receive timestamp in integer nanoseconds, an event-id chain that makes any gap visible, and one normalized schema across 35+ venues — the same capture our own high-frequency trading engine and enterprise feeds run on.

€1 per instrument-day

Any instrument-day is €1, series-day bundles start at €1 — no subscription, no minimum order, no tiers to unlock. Credit packs lower the effective price and never expire, and every venue has free full-day samples to test against first.

Self-service for everyone

Pick the days in the Data Shop, pay by card as a guest and download immediately — no sales call, no enterprise contract, no KYC. Coding agents buy the same files through the MCP server, and the free Agent Skill teaches them the format.
