Conid to ticker

how can I link conid to ticker?

Check out quantrocket master get (CLI) / quantrocket.master.download_master_file (Python)

great, that what I needed!

so SecType=STK is for both stocks and ETFs.
and when Etf=1 => that's an ETF not a stock.
right?
any other that would go under SecType=STK?
