Positions
A position represents the holdings of a specific instrument in a user’s account.
How positions work
When your first buy order is filled (i.e. fully executed), the resulting quantity of the instrument purchased will be represented as a position that can be queried via the Investment API. Placing buy and sell orders, corporate actions and account transfers can all change the quantity of your securities position.
Securities positions are tracked at account level, which means that a user can hold multiple positions in the same instrument.
