How can I change the month or year for a contract?

You can change the month or year of a contract within your quotes by right-clicking on the quote to roll-forward or backward depending on the contract month/year you are looking for.

You can now right click in the new contract and drag any modules you would like to add to your layout (DOM or chart).

If you have Link to Quotes enabled on your chart, it will automatically update the chart when you click on the new contract's quote.
