Smart Ticker Search

The search_by_ticker tool automatically tries multiple security types when searching, so you don't need to know if a stock is common or preferred:

# These all work automatically:
AAPL US    → Common Stock (Apple)
VOW3 GY    → Preference shares (Volkswagen preferred)
P911 GY    → Preference shares (Porsche)
RR. LN     → Common Stock (Rolls-Royce)
BA. LN     → Common Stock (BAE Systems)

If you need to search for a specific security type, you can use the optional securityType2 parameter:

securityType2	Description
Common Stock	Regular common shares
Preference	Preferred/preference shares
Depositary Receipt	ADRs, GDRs
ETP	ETFs and other exchange-traded products
