Book Open/Close Trades for Options on Futures with Variation Margin

In the Option with Variation Margin panel, you can manually book an open (buy) and close (sell) trade for an option on a future with variation margin. Options on futures with a variation margin are valued by comparing the current contracts held at the current day's closing price to the prior day's closing price. This amount is typically settled as a cash movement the following morning as part of the variation margin process.

This article assumes you are familiar with the entity and security level elections that have been made for processing an option on a future with variation margin. For example, you must enter a value for the Net Option Positions field. If you set this field to Yes, you can only open (buy) the option long. The short positions are represented by negative quantities. The transaction elections are buy and sell. If you set this field to No, you can open (buy) the option either long or short and the contracts are displayed as positive numbers. The transaction elections are buy, write, sell, and buy to cover. Also, you must enter a value for the Expiration Delay Days field. If there is no value, the system automatically expires the option on the expiration date, preventing entry of an exercise trade on that date. You can access these fields using the Create/Edit Entity panel.
