Subscribe to the account information channel to keep track of your margin info. The account information channel will provide a feed of your margin info for as long as the channel remains open. Any authenticated connection is automatically subscribed to the account information channel.

Example code to open an authenticated connection can be found on our Authenticated Channels Page.

Margin info events are sent with CHAN_ID = 0 and can be identified by looking at the TYPE stream field. Margin info events can be recognised by the 'miu' (margin info update) abbreviation.
