What this is
Market Volume Pulse highlights attention, not conviction. Heavy volume can mean news, rebalancing, options hedging, ETF flows, panic, hype, or plain liquidity.
Important: free mode uses delayed public quotes plus a high-liquidity watchlist. A configured Alpha Vantage key can add a broader most-active feed. Market context only, not financial advice.
