Trading volume is encoded in the logarithmically scaled thickness of each candle. An S&P 500 and NASDAQ-100 correlation matrix with hierarchical clustering, rolling correlation charts, and a minimap. It contains over 250,000 cells and correlates over 30 million data points. S&P 500 and NASDAQ-100 constituents are represented as spheres in a 3D space spanned by close price, 24H volume, and 24H change. Density-based spatial clustering groups similar constituents, while regression planes show how each axis is predicted by the other two. The material on this website is for…from timedoor.xyz
