Hummingbot Connector changelog

A cancel release, for venues moving markets onto Ecosystem 6.5.0's shard tier. On a sharded market the order rows this connector reads are a projection that lands a few milliseconds after the shard has the order, and a bot that cancels straight off its plac…

A paper-trading release. A strategy can now be run against your exchange's real order book with simulated money — the same spreads, the same ladder, the same refresh interval — without one order reaching the matching engine or one wallet being debited.

CONNECTOR · PAPER-TRADING · SIMULATION · STRATEGIES · INSTANCES

A funding release, and a narrow one: the two surfaces this connector offers for the same number disagreed with each other. The REST funding-rate endpoint reported what the platform settles. The live websocket stream reported what somebody typed into the mar…

CONNECTOR · FUNDING · WEBSOCKET · MARKET-DATA · FUTURES

Three fields this connector reported to professional counterparties were statements about the platform rather than about the market, and all three have stopped being. The perpetual funding endpoint served a hardcoded zero rate to every caller that asked. Th…

Three things a two-sided market maker could not do: place a market order, hedge on paper, or stop its bot without losing orders it placed by hand.

CRITICAL FIXES · ORDERS · MARKET MAKING · BOT CONSOLE · STRATEGIES

A market maker that cancelled several quotes at once made its own order book read as empty for the next few seconds — and was then refused for insufficient liquidity against a book that was full.

v6.0.8 fixed a cancel that was given up on. This fixes the one that was never sent — and three other ways a bot could stop trading without saying so.

CRITICAL FIXES · ORDERS · MARKET MAKING · CONNECTOR · PERFORMANCE · BOT CONSOLE · STREAMS

A stuck-order release, and it is the most damaging fault this connector has had. When the exchange refused a cancel — a rate limit, a bad gateway, a dropped connection — the connector gave up on it silently. Hummingbot stopped tracking the order; the exchan…

If you run a PMM strategy on this connector, it has never placed an order.

An admin release. Nothing in the connector, the exchange API or the bot-facing paths changed — a bot that trades today trades identically after updating, and there is no connector to reinstall.

ADMIN · API KEYS · TRANSLATIONS · PERMISSIONS · ACCESS CONTROL · KILL-SWITCH · RATE LIMITS · AUDIT LOG · +4

Version 6.0.3 fixes order placement, which was failing 100% of the time, and order cancellation and lookup, which returned "not found" for every request. Between them these made the connector unusable for trading. On current Hummingbot releases the connecto…
