### <summary>
|
|
### This algorithm tests and demonstrates EUREX futures subscription and trading:
|
|
### - It tests contracts rollover by adding a continuous future and asserting that mapping happens at some point.
|
|
### - It tests basic trading by buying a contract and holding it until expiration.
|
|
### - It tests delisting and asserts the holdings are liquidated after that.
