Did you ever figure this out?

I was searching for the option to disable rate oracle since I was getting spammed by rate oracle errors as well, but I couldn't find any documentation.

Check here: https://hummingbot.org/strategy-configs/rate-oracle/ no mention of rate_oracle_enabled. Also, CLI does not hint at this option.

Meanwhile, I am suspicious of spam error messages that max out CPU utilization. I am experimenting with eliminating spam to check if it solves CPU issues.
