بحث موثق بالمصادر: Kraken Cancel ON Disconnect

Decision outcome: Keep the bot in paper, sandbox or read-only mode until disconnect handling, order expiration, cancel behavior, fill reconciliation and duplicate-order prevention are tested with non-secret evidence. Do not infer a venue-level safety feature from a separate endpoint or order type.

The evidence snapshot was taken at 2026-09-20T08:45:00.000Z. The source set for this package is Kraken Docs, Kraken Docs, Coinbase Developer Docs, Coinbase Developer Docs. A local topic queue, a previous NexuAlpha page, a social repost, a price feed, a search snippet, a cached draft or a synthetic test was not treated as proof. Those inputs can suggest a question, but the article only makes claims that map to the public source list for this article.

Verified facts. Claim c1: Kraken documents a cancel-on-disconnect control for futures API trading, so disconnect behavior can be treated as an explicit bot design question rather than an afterthought. Claim c2: Kraken WebSocket documentation separates streaming state from trading action, which means a bot still needs its own reconciliation path after connection loss. Claim c3: Coinbase Advanced Trade documentation describes fulfillment policies such as GTC, GTD and IOC and maps them to order time-in-force behavior. Claim c4: Coinbase documentation states downside protection in bracket orders is not guaranteed during high market volatility, so bots cannot treat an attached order as absolute risk removal. Each claim is deliberately narrow. It does not prove personal eligibility, future availability, execution quality, regulatory status beyond the cited wording, tax treatment, recovery outcome, wallet safety, investment suitability, liquidity depth, or platform solvency.
