# Deprecated - use chart instead
yf historical AAPL '{"period1":"2024-01-01","period2":"2024-12-31"}'

# Recommended: use chart
yf chart AAPL '{"period1":"2024-01-01","period2":"2024-12-31"}'

Examples

Quick Price Check

# Full JSON then filter with jq
yf quote NVDA | jq '{symbol: .symbol, price: .regularMarketPrice, changePct: .regularMarketChangePercent}'

# Using historical (deprecated, but still works)

Troubleshooting

Cookies: The tool automatically handles cookies (stored in ~/.yf2-cookies.json). If you encounter issues, try deleting this file.
JSON Output: The output is pure JSON. Use jq to parse it for scripts or readability.

Additional tips:

If you see authentication or parsing errors, delete the cookie file and retry:

rm -f ~/.yf2-cookies.json
yf quote AAPL

On macOS with zsh, prefer single quotes around JSON option arguments and use double quotes inside (see examples above).
If you want a compact numeric value only (no jq), use a short jq filter, e.g.:

yf quote AAPL | jq -r '.regularMarketPrice'
