Investment Analysis Workflow

When the user asks about stock performance, portfolio advice, or market analysis:

• Get live data via CLI — quotes, positions, K-line history, intraday

• Get news/catalysts via CLI — prefer Longbridge first; fall back to WebSearch only if insufficient

• Combine — price action + volume + catalyst → analysis + suggestion

# Market data
longbridge quote SYMBOL.US
longbridge positions                # always pull when user asks about "my portfolio"
longbridge kline history SYMBOL.US --start YYYY-MM-DD --end YYYY-MM-DD --period day
longbridge intraday SYMBOL.US

# News & content (prefer these over WebSearch)
longbridge news SYMBOL.US           # latest news articles
longbridge news detail <id>         # full article content
longbridge filing detail <id>       # regulatory filing (earnings reports, etc.)
longbridge topics SYMBOL.US         # community discussion
longbridge market-temp              # market sentiment index (0–100)

# Account statements
longbridge statement list           # list available statements
longbridge statement export --file-key <KEY> --section asset equity_holdings  # account summary
longbridge statement export --file-key <KEY> --all                          # export all non-empty sections

Only fall back to WebSearch when Longbridge news is insufficient (e.g., breaking news not yet indexed, macro events unrelated to a specific symbol).
