Hummingbot — Market-Making & Arbitrage Bot · Release v2.16.0 · 2026-07-29

Open-source market-making and arbitrage bot Hummingbot released v2.16.0. Gemini exchange connector added; Cube, AscendEx, and Vertex connectors removed. Order handling, balance calculation, and rate-limit bugs fixed for major connectors including Binance Perpetual, Backpack, Hyperliquid, and Pacifica. LP (liquidity provision) executor position cleanup logic and backtesting compatibility also improved.

weltiq perspective: For weltiq users backtesting or running Hummingbot strategies, expanded Gemini support and improved stability of major exchange connectors reduce errors and increase execution accuracy.
