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 are Time Iterators like the connectors and the strategies. 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_sizeand enter the desired tick size in decimal form.
- Stop and exit Hummingbot then edit the
conf_client.ymlfile located inside the
hummingbot_conffolder using a text editor. Look for
tick_size: 1.0and change
1.0to whatever tick size you want. Save the changes to the yml file then run Hummingbot again for the changes to take effect.
Due to connector limitations, the tick size cannot be set lower than
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
