Workflow

1. Identify which ETF(s) the user is interested in; default to all 11 SPDR sectors if none specified.
2. Fetch real-time quote and volume for each ETF.
3. Fetch recent daily OHLCV to compute 5-day / 20-day volume trend.
4. Fetch intraday capital flow if available.
5. Rank ETFs by net inflow signal; identify top-3 inflow and top-3 outflow sectors.
6. Synthesise sector rotation narrative and risk-appetite assessment.

CLI

# Real-time quote + volume
longbridge quote <ETF_SYMBOL> --format json

# Recent price + volume history (20 trading days)
longbridge kline <ETF_SYMBOL> --period day --count 20 --format json

# Intraday capital flow
longbridge capital <ETF_SYMBOL> --format json

Output

1. Ranked table: ETF | Sector | Today's change | Volume vs 20-day avg | Flow signal
2. Top inflow / outflow sectors highlighted.
3. Narrative: what the rotation pattern implies for risk appetite and market leadership.
