Could you build this?
Partial A wrapper UI is trivial, but building a high-performance HTML5 Canvas charting engine with sub-pixel rendering, smooth pan/zoom, technical indicators, and frame-rate optimization requires deep graphics math.
What it would actually take: Requires building an imperative 2D rendering engine on HTML5 Canvas handling coordinate transformation matrices, responsive HiDPI/Retina scaling, collision detection for drawing tools, and optimized numerical algorithms for technical indicators (SMA, EMA, MACD) without rendering lag.
