Clock tick size

Starting with version 1.8.0, the tick_size is now added as a variable in the ClientConfigMap, this means that you will be able to change the value of the tick size in the conf_client.yml file or by running config tick_size from within Hummingbot.

How it works

All the major components of Hummingbot, like the connectors and the strategies inherit from the TimeIterator class. The Clock notifies all the components involved in the strategy by calling the method c_tick() of the time iterators every tick_size.

By default, the tick_size (or how long it takes Hummingbot to loop through a strategy iteration) is currently set to 1 second.

How to configure Tick Size

There are two ways to configure the tick size

• From within Hummingbot, run the command config tick_size and enter the desired tick size in decimal form.

• Stop and exit Hummingbot then edit the conf_client.yml file located inside the hummingbot_conf folder using a text editor. Look for tick_size: 1.0 and change 1.0 to whatever tick size you want. Save the changes to the yml file then run Hummingbot again for the changes to take effect.

Note

Due to connector limitations, the tick size cannot be set lower than 0.1 seconds

To check what the current tick_size is, you can run the config command and check the tick_size value under the Global Configurations section
