Summary

Monday SDK batch for the Bitget UTA changelog through 15 Oct 2026, checked against https://www.bitget.com/docs/uta/changelog/2026-10 and the live public API. Version 3.2.6. Base 71d95ec.

getServerTime now calls GET /api/v3/market/time. The old /api/v3/public/time path returns 404, so clock sync was broken.

Changelog

• CFD GET /api/v3/cfd/trade/history-order: request cursor (last orderId from page 2 on) and pageNo. First page may return more rows than limit.
• getOpenInterestHistory - GET /api/v3/market/open-interest-history (symbol, period 5m..1d).
• getInterestRateHistory - GET /api/v3/market/interest-rate-history. VIP query param is level (vip0-vip7, pro1-pro6). vipLevel is ignored by the API. limit and cursor work live.
• getServerTime returns serverTime (ms) and serverTimeMicros.
• getAnnouncements - GET /api/v3/public/annoucements (Bitget spelling). Live rows use cTime and annDesc. Docs call the time createdTime.
• getCoins - GET /api/v3/market/coins. Live chains use withdrawMinScale. The docs example names that field withdrawPrecision.
• Instruments: fullName, instrumentType (metal/energy/stock/etf/crypto), marketRegion, isin. symbolType is unchanged. Crypto returns marketRegion and isin as null.
• Place order and batch place: requestTime + receiveWindow ([10, 60000] ms). An order that arrives after requestTime + receiveWindow is canceled.
• Place order, WS place-order, and order info: venue (internalization | lit_market) and rTokenTimeInForce (gtd | gtc, gtc is 90 days). place-reality-order gets the same optional fields. The 13 Oct changelog describes them for that endpoint. Its parameter table does not list them yet.
• Rate-limit quota: a sub-account may call get/set for itself. uid / uids are not required and are ignored on that call. The master account still must send them.
• getMaxOpenAvailable: marginMode (crossed default, isolated). Isolated available excludes futures trial funds.
• Unfilled strategy orders: response side.
• STP groups (MM whitelist): createStpGroup, getStpGroups, addStpGroupMembers, removeStpGroupMembers. uids is a comma-separated string, max 50.
• getRealityOrderBookSegmented and WS topic reality-orderbook-segmented. Levels are [price, onshoreQty, offshoreQty], up to 50. Whitelist required. Go-live 20 Oct 2026. Pairs that have not finished the matching-engine upgrade do not return data. A crossed book after the upgrade is expected.
• Public topics books1 and books5. books1 and books5 are full snapshots on every push. books and books50 are a snapshot, then incremental updates. rToken: books1 pushes at all times. books5 / books50 / books push only outside US market hours. REST orderbook for rToken returns only the BBO during weekday market hours.
• UTA financial-record type is the official enum from https://www.bitget.com/docs/uta/enum, including Bitget's MARIN_BUY_DEAL / MARIN_SELL_DEAL spelling.

Checked, no SDK change:

• books50 helpers and examples do not assume a full snapshot. There is no local orderbook merger. The V3 public example only logs raw messages. The existing WsOrderBookDataV3 note already said snapshot then incremental. JSDoc now also separates books1/books5 (always a snapshot) so that note is not applied to them.
• UA account-update balanceOriginal was already on WsAccountCoinV3 and REST AccountAssetV3 (new coin balance, without deducting borrow).
• UA deposit dest (on_chain | internal_transfer) and status (pending | success | fail) already match Bitget.Net TransferType / TransferStatus. Withdrawal dest matches. Withdrawal status already matches WithdrawStatus.

Checks

• npm run build
• npm run lint (eslint src + apidoc prettier)
