In importing an instrument list via Tools you are able to set the exchange to use. The issue is 9 out of 10 times the comma separated list that is added to that dialog box contains symbols of say both NYSE and NASDAQ however you may only select a single exchange when importing.
For example you create an instrument list that contain 200 items and 50% are traded on the NYSE and 50% are traded on the NASDAQ however NYSE was the option selected for importing.
Question: Is using the Update Instruments function, General Properties & Symbol Mappings, suppose to update the exchange in which that instrument is traded on?
In testing this it does not. I found a symbol that was set to NYSE but should have been NASDAQ, performed the update, then reviewed that Instruments properties and only Default & NYSE was selected. If this is set wrong does it have any affect when using IB as the broker?
Thanks,
