How Chart Vision works
BackgroundBorder pixels give the theme (light/dark) and background colour.
Colour masksHSV thresholds isolate rising and falling candles; small specks are removed.
Grid & plot areaMorphological line filters find gridlines and the plot rectangle.
CandlesColumn runs split candles; row widths separate body from wick.
Price axisTesseract OCR reads axis labels; a robust fit maps pixels to prices.
AnalysisVolatility, drawdown, trend, Value at Risk and the likely range of the next candle.
