I think that's a important function we need.
Like futures have it's settlement date every month.
Each commodity has a different settlement date.
After the current month's contract settles, you can only trade the next month's contract.
There will be price differences between different months' contracts.
Therefore, most people automatically close their positions on the current month's contract settlement date and start over with a new contract, rather than rolling over positions.
