Broker with oil contracts

I am looking for brokers with oil contracts for a few months ahead, minimum 2 or 3 consecutive contracts.
All the brokers I know only offer to trade on one nearest contract or spot oil.

Do you know any brokers who meet my expectations.?

A good broker is very important to make a good strategy and earn money from this market.

This picture explains exactly what I would like to trade …
… at least two, three or more consecutive series of contracts in parallel.
These can be real futures or in the form of CFDs.
