In this article, we will consider how to create multi-colored indicators or convert the existing ones to multi-color. MQL5 allows to represent the information in the convenient form. Now it isn't necessary to look at a dozen of charts with indicators and perform analyses of the RSI or Stochastic levels, it's better just to paint the candles with different colors depending on the values of the indicators.
An anti-aliasing algorithm of the CCanvas class is the base for all constructions where anti-aliasing is being used. The article contains information about how this algorithm operates, and provides relevant examples of visualization. It also covers drawing shades of graphic objects and has a detailed algorithm developed for drawing shades on canvas. The numerical analysis library ALGLIB is used for calculations.
