Release Notes - Version 1.8.0

Released on September 30, 2022

We are very excited to ship the September 2022 Hummingbot release (v1.8.0) today!

Variable Tick Size

Previously, the default tick size (how long it takes Hummingbot to loop through a strategy iteration) was set at 1 second. Now, users can adjust this setting and define a custom tick_size parameter.

  • 5649 added tick_size as a variable, allowing the tick size to be changed in the conf_client.yml file or by running config tick_size
