Table 1-1 Own Portfolio Functions

Function	Description
Opening long and short positions:	You can book contingent entries for the Long and Short positions opened during the day. You can define the premium exchange involved in Option Style options and book the premium amount. You have the facility to define and book the brokerage amount and charges involved in the deal.
Closing long and short positions	You can reverse contingent entries for all closed contracts. You have the facility to calculate the closing gain and losses, and book appropriate entries for the same.
Revaluation of Futures and Options	As part of the End of Day (EOD) activities, you can perform realized revaluation on futures and future style options based on the closing price of the instrument and the series. For option style options, you can perform a Memo or Notional revaluation for the entire portfolio depending on the frequency that you choose to maintain.
Exercise of Options	Facility to reverse the contingent entries for exercised contracts Facility to calculate the exercise gain based on the difference between the price of the underlying asset, the Strike Price of the instrument, and book accounting entries for the same.
Assignment of Options	Facility to reverse the contingent entries for exercised contracts. Facility to calculate the assignment loss based on the difference between the price of the underlying asset, the strike price of the instrument, and book entries for the same.
Exchange of futures for physicals	Facility to reverse the contingent entries while exchanging futures for physicals. Facility to calculate the exchange loss or gain based on the difference between the price of the underlying asset, the acquisition price, and book entries for the same.
Expiry of Options	On the expiry date, if the series is Out of the Money, the system will process an automatic expiry for the series. Similarly, if the series is In the Money, an automatic exercise/assignment of options event will be processed. The system also calculates the expiry loss or gain depending on whether it is a long or short deal. The respective accounting entries are also booked.
Expiry of Futures	In the case of futures, on the expiry date, the system automatically exchanges futures for physicals. Note: While exercising and assigning options, or during the expiry of options, and futures only the price differential (that is, the Exercise Gain or the Loss) will be processed by the ETD module.

For options, the price differential is the difference between the spot price of the underlying asset and the strike price of the instrument. For futures, the price differential is calculated as the difference between the spot price of the underlying asset and the acquisition price of the instrument.
