The CandelCode (CNDL) indicator is based on the article ``Coding Candelsticks'' published in Technical Analysis of Stocks and Commodities (November 1999) by Viktor Likhovidov.
Two parameters are used to initialize the Bollinger Bands necessary to calculate all required thresholds; the standard deviation number is set to 0.5 with a period of 55.
