Occasionally users find symbols which aren't in the database, or have confusing symbol names. If you have issues with this please post the missing symbols to this thread and we'll find the corresponding one for you or flag it to be fixed. If possible please read the QuantQuote symbol list and see if its on there first: https://www.quantconnect.com/files/symbols.csv - this is the list we use to check the symbols exist before rejecting the security.

QuantQuote uses a numbering system to track repeated symbols -- you can read more information about TickMap here: https://quantquote.com/products_features.php
