Expiry Rates Rules

General Information

10trade offers a variety of asset classes for its clients such as stocks, currencies, commodities and leading indices.

If you wish to trade an asset which is not offered on our platform, feel free to contact us by phone or via support@10trade.com and we will do our best to add the requested asset.

The following expiry rules apply to all assets according to the asset class:

Currencies: (Bid + Ask)/2
Stocks: (Bid + Ask)/2
Commodities: (Bid + Ask)/2
Indices: (Bid + Ask)/2

Relevant terms used to calculate the expiration rate

Bid — The last known price prior to the options expiration time, for selling an asset.

Ask — The last known price prior to the options expiration time, for buying an asset.

Last Quoted Price — The last known price prior to the options expiration time that was actually played for the asset. (This price may be the same or different than the bid or the ask prices).

Indices such as the Dow Jones or the FTSE are calculated based on the last traded price of all the stocks listed in the index.

Stocks and currencies have quotes of Bid and Ask. E.g. for Citigroup and Google stocks there is a price for buying the asset and a price for selling the asset, therefore 10trade  calculates the expiration price as the mid-price which equals to (Bid + Ask)/2.
