Conclusion

For best performance we recommend running a data node to prevent latency. If you compare all three logs, the third bot created orders and completed proper shutdown upon sending the stop command all within a minute while the first two bots took several minutes (bot #1 failed to shutdown properly) to respond to the stop command and close orders.

However, running a data node with significant usage may incur $1000 or more in monthly cloud server costs.

Cost

Provider: AWS

Server specs: t3.2xlarge | 8vcpu | 16GB RAM | 2000 GiB

Cost estimate for two weeks (338.868 hrs) running data node: $494.23

Test Parameters

Script Used: v2_generic_with_controllers.py

Controller: bollinger_v1

Server Node + Hummingbot client running on AWS - Asia Pacific (Tokyo) Server

This was a quick test to check latency in creating orders, balance check was run at start then the script started with the controller config. After creating the first orders, the stop command was then issued.
