The first part of the "Bankable Asset API" is "Trading", which was developed by the OpenBankingProject.ch Community with a lead of Avaloq. 

It consists of the following pieces:
• securities orders
• foreign exchange swap orders
• foreign exchange single-leg orders.

This covers all kinds of trading instruments in the API.
All definitions follow the ISO Standard. Relevant aspects of the fixed protocol have been considered in the definition. In aspects around bankable assets, there will be interaction with other initiatives

The APIs are open source and thanks to a structured change management process it is possible to place change requests in case of problems or further requirements
