https://grafioschtrader.github.io/gt-user-manual/en/watchlistinstrument/instrument/securityderived/security/securitylookup/index.htmlA new security requires up to four connectors with their URL extensions as well as details such as name, ticker, maturity, distribution frequency and denomination. The lookup at the data providers determines these details from ISIN, currency, stock exchange and asset class. It checks every proposed connector with a request for real price data before you take it over. For the freely accessible data providers neither GTNet nor a paid subscription is needed.Hugoen
