BTC Daily Direction Explorer is a free, browser-based tool that classifies and visualises Bitcoin daily price direction and trading volume. Each trading day is categorised as up (close greater than open), down (close less than open), or unchanged, and explored through interactive charts including a daily direction treemap, a price-move vs volume bubble chart, and a volume-vs-move scatterplot. It uses BTCUSDT daily price data (00:00 UTC boundary) with aggregated Binance and Coinbase BTC spot volume. This tool requires JavaScript to display its interactive charts. It is a visual prototype and not financial advice.
