In an AddOn, is there any way (supported or unsupported) to programmatically determine if a particular Instrument is being provided by a particular Account/Connection?
For example, if I connect to an FXCM Account, can I discover, or alternatively, can I query, if a particular currency pair (e.g. USDTRY) is actively in the data stream? [Note: this is just an example -- it could be any broker, any Instrument type, any Instrument.]
Thanks.
