Summary

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 .

The idea under this PR is to let the user modify the tick size by using a config variable because currently the tick size is not configurable and by default is 1 second.

Adding a tick size config variable to the conf_client.yml will let the user change it by modifying the yml, using the command config tick_size in the client or with the extra argument in the start that will be —tick-size.

In the PR are implemented the two options, but I created a poll in Discord to see if the community wants the two solutions or just one of them. If the result is that they only want just one, I will delete the other one. Link: https://discord.com/channels/530578568154054663/557343500908363786/1014877021203091487

Rules:

• If the argument —tick-size is not used in the start command, the default tick_size of the conf_client.yml will be used
• By defaul the tick_size will be 1 second.

The changes in the code include:

• Fix the issue The conf_client.yml is not created when Hummingbot starts #5648 .
• Add the tick_size 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 or by running config tick_size.
• Add an argument in the start command that let you override the tick size.
• Add parameter to the config command and the test related.
