I saw in the log the following entries: Account Rate Limits: 1200 requests per minute, 50 orders per 10 seconds, what does it mean?

When MoonBot starts the terminal, it logs service information, in this case reports about API limits, that on this account, you can send no more than 1200 requests per minute and place 50 orders in 10 seconds. If these limits are exceeded, the exchange gives a short-term ban, if after its expiry date the limits are exceeded again, the ban will be repeated for a longer period. Thus exchanger insures itself from increased load on its servers.
