Riset terverifikasi sumber: Crypto Exchange Market DATA

Decision outcome: Before a market-data feed drives orders, score the venue against the radar fields and keep the strategy read-only until schema changes, reconnects, missing messages and account-state reconciliation are handled.

Evidence snapshot. This article was researched at 2026-09-20T17:37:04.406Z using Binance Developers, Coinbase Developer Docs, Kraken Developers. The article does not use a local queue, old draft, search snippet, social repost, price chart, market rumor or AI summary as proof. Those surfaces can suggest what to ask, but the material claims below must map to the public source IDs listed for this article.

Verified facts. Claim c1: Binance provides SBE market-data documentation. Claim c2: Binance provides WebSocket stream documentation as a separate market-data surface. Claim c3: Coinbase provides an Advanced Trade WebSocket overview for subscriptions and connection behavior. Claim c4: Kraken documents Spot WebSocket v2 for real-time channels, which makes channel semantics part of the radar score. These facts are deliberately narrow. They do not prove account eligibility, execution quality, future availability, legal status beyond the cited wording, tax treatment, customer support outcome, redemption success, liquidity, consumer protection or regulatory approval for a particular user.

Comparison discipline. For crypto exchange market data schema versioning disclosure radar, the useful answer is not a universal winner. It is a source-bound scorecard: which official source answers the immediate question, which control is still blank, which blank changes user risk, which test is reversible, and which condition reopens the decision. An honest blank is safer than an invented advantage.

FAQ. What is the short answer? NexuAlpha Radar scores a market-data integration as decision-ready only when the venue exposes schema identity, channel semantics, endpoint separation, heartbeat or liveness behavior, reconnect guidance, authentication boundary and a reconciliation path. What should be verified first? Verify the official source and the exact control surface. What should not be inferred? Do not infer eligibility, future support, legal treatment, tax treatment, recovery, execution quality, liquidity, redemption, consumer protection or account approval. When should the user stop? Stop when source, object, user state, permission, route, issuer, jurisdiction or failure handling is unclear.
