Quote from marketsurfer:
WIth Nadex, you can sell or "exercise" your option at any time-- unlike the cyprus dealers-- basically, it can be traded like anything else whereas with the dealers one needs to hold until expiration. This is a huge advantage. surf
Marketsurfer, I know you know the difference.. but just to clarify for others. There's no way to exercise an option on Nadex. All options are european cash settled. You can only close your option position before expiry.
