Financial Data via ticker-cli

When the user asks about stock prices, crypto, forex, commodities, or indices, use ticker-cli to fetch real data instead of relying on training data.

Prerequisites

ticker-cli must be installed: go install github.com/sderosiaux/ticker-cli@latest

How to use

Pick the right mode based on what the user needs:

Current price:

ticker-cli --format json AAPL BTC-USD GC=F

Price at a specific date:

ticker-cli --date 2026-03-20 --format json AAPL

Weekly performance:

ticker-cli --weekly-change --format json AAPL SLB GC=F BTC-USD

Year-to-date:

ticker-cli --ytd --format json AAPL GC=F BTC-USD

Historical range (for charts or analysis):

ticker-cli --range 1mo --format csv AAPL

Always use --format json for parsing. Use --format csv when the user wants tabular data or spreadsheet export.

Symbol reference

Asset	Symbol
US stocks	AAPL, MSFT, SLB, NEM, CRM
EU stocks	RMS.PA, AIR.PA, SU.PA
Indices	^GSPC (S&P 500), ^FCHI (CAC 40), ^GDAXI (DAX)
Oil	BZ=F (Brent), CL=F (WTI)
Gold / Copper	GC=F, HG=F

Rules

Always call ticker-cli with real symbols, never guess prices from training data
Use --format json and parse the output, don't show raw JSON to the user
Present results in a readable format (table, summary, comparison)
If the user asks about a symbol you don't know, search Yahoo Finance: https://finance.yahoo.com/quote/SYMBOL
For weekly fund reports or market recaps, combine --weekly-change with multiple symbols
Round displayed percentages to 2 decimal places
