Release Notes - Version 1.12.0

Released on January 27, 2023

We are very excited to ship the January 2023 Hummingbot release (v1.12.0) today! See below for the highlights in this release.

Epoch 3 Polls Changes

Recently, we finished the first set of Polls, a new initiative that lets HBOT holders decide how the Foundation allocates its engineering bandwidth and developer bounties across the components in the Hummingbot codebase. Based on the results of the Polls, below are the outline of the changes made initially in this release.

  • Adjusted the documentation pages for each Exchange Connector and Strategy
  • Removed exchange connectors that did not meet the Minimum Voting Power Threshold from the codebase
  • Removed Fixed Grid and Arbitrage strategies since they did not meet the Minimum Voting Power Threshold
  • Running the connect command reflects the CEX connector tiers (Gold, Silver, Bronze), also a new command was added gateway list to display all available DEX connectors and their tiers

For more details of the Epoch 3 poll results check out this blog post:

Orchestration Module Phase I

Last year, the community voted to allocate a bounty to fund development of an orchestration module that lets users control multiples instances of Hummingbot. See this Notion doc for an overview of the project.

Phase 1 will provide a clean communication and messaging layer and allow for remote control and monitoring of multi-bot environments in a distributed context. Meaning that bots can "live" on different machines and infrastructures (e.g. having a bot local and another bot on AWS).

To achieve this approach, Phase 1 implements an MQTT layer for bots to connect remotely to message brokers, as a single point of reference, using asynchronous bidirectional communication channels (push/pull). In this architecture, bots can be considered as clients to the overall environment. Bot scaling is seamless and does not require any further setup, anyone can connect any number of bots the a message broker (e.g. RabbitMQ, EMQX etc) without any other dependencies.

Outline of the features included in Phase I

  • Interface to execute remote commands - Start , Stop , Import , Config strategy, Balance , Change balance limits

  • All these commands can be called using an unified web application that also receives the following information from the bots - Heartbeat - Status, PNL - History

  • The configuration of the broker in the client should be in the conf_client.yml file

See this page for a requirements doc for this project and past discussions.

hedge Strategy Updates

Key changes:

  • Add more info to facilitate debugging.
  • Refactor the status screen and add more information and log
  • Fixed position name referring to True and False to ONE-WAY and HEDGE
  • Fixed issues related to typing
  • For hedge by amount, a. change the matching of pairs from the match by trading pair to match by base asset b. change hedge price calculation for hedge by the amount to use mid-price instead of VWAP price. i. This is mainly used to calculate the market price to put since hummingbot only allows limit orders. Users can still increase slippage to guarantee their trade is made.
