Drawing tools and annotations let you add geometric overlays to stock charts for marking support/resistance zones, trend channels, and other technical patterns directly on price data.
This sample renders ORCL daily candlesticks with an Andrews Pitchfork annotation tracing a three-point trend channel and a filled rectangle highlighting a consolidation zone. Custom HTML tooltips handle missing-data periods gracefully, and major/minor grids improve value readability. A synchronized candlestick scroller with range picker and selector controls enables interactive period analysis.
