You will see in the software there are two links, one called requests per/sec, the otherBetfair Charges.
Betfair Charges outlines the charges Betfair can make depending on your betting and usage of the API.
The one of concern is the amount of data requests/sec you make to the Betfair API which has to be lower than 20/sec or they will charge you.
Betbotpro doesn’t really get close to this figure so you should have nothing to worry about.
A counter is provided at the bottom of the software to show the number of requests/sec.
You should be careful though if running multiple bots or other software that uses the API as it could add up to more than 20/sec and you could be charged.
The are currently no data charges for the new Betfair API-NG based software
