Continuous Contract Charts

X_STUDY provides the ability to create continuous contracts. A continuous contract chart contains several expiry months spliced together to form a seamless chart. You can create a continuous contract definition defining how and when the expiry months are spliced together, and then apply the definition to a product.

To create a Continuous Contract Chart, select WindowX_STUDY | Continuous Contracts from the X_TRADER Control Panel. This displays the Continuous Contracts dialog box.
