Contract rollover error

[Aporshnev]

When I try to rollover a contract, I am offered to switch to December 2020. According to the specification, the next contract is July. What do I need to do in the platform to move to the next month instead of the end of the year?

Hello,

Thanks for writing in today.

The rollover window would be a suggested contract based on historical volume tendencies, and you would be able to use the BZ 06-20 instrument as well by typing BZ 06-20 directly on a chart, I am able to see this contract exists and plots in the platform as well. It appears to have a lower volume and doesn't appear to be so liquid, as a consideration.

Please let me know if I may be of any further assistance.
