Exercising Options

If you hold a long position in options (put or call), you can demand certain considerations from the counterparty who sold you the options. This process is called exercising options. We lead you through the process.

Exercising Options in TWS

Within the TWS, simply click on Trade in the menu bar, and then select Option Exercise.

In the Option Exercise window, under Long Positions, click Select in the Exercise Action column for the option(s) you want to exercise.

By clicking on Select, you will see two choices: Exercise Early – All and Exercise Early – Partial. The latter one becomes available if you hold more than one option contract. If you choose this option, you will need to specify the quantity of option contracts you want to exercise. Simply enter the appropriate quantity in the designated field and confirm by clicking OK button.

If you have a single contract that you wish to exercise, or if you want to exercise all contracts in a position, just click on Exercise Early – All.

A blue T-button (Transmit) now appears in the right-hand column. Click on the button to submit a request to exercise.

Exercising Options in Mobile App

Navigate to the main menu and tap Option Exercise/Roll. Next, under Long Positions, tap the option position you want to exercise and select Exercise Options.

If you hold multiple option contracts within the position, please specify the quantity of options you wish to exercise in the designated field. After confirming your selection, tap on Submit Instruction to proceed.

However, if your option position consists of only one option contract, you can simply tap the Submit Instruction button.

LYNX does not charge any fee for exercising or assigning an options. However, third party costs may be charged for some options. Please consult your local LYNX website tariff page for the associated costs.

Standard commission for index options in Europe and futures options worldwide is charged at expiration of the contract.

No third-party costs charged for the delivery of a long or short position resulting from the exercise or assignment of U.S. index and stock options in Europe.

On the expiration date, options are settled through either cash settlement (applicable to European-style options) or physical delivery of the underlying asset (for American-style options). Cash settlement involves calculating the difference between the exercise price and the option’s settlement price. You will either be credited with the funds or have the amount debited from your trading account. On the other hand, physical settlement entails the receipt or delivery of the underlying asset.

For more information on the settlement of individual financial instruments, please refer to this link.
