The indicator paints candles going beyond the Rj_SlidingRangeRj_Digit channel. Candlesticks outside the channel limits are marked with color according to the trend. Candlesticks with the trend have bright fill color, ones against the trend - dark fill color.
The indicator algorithm features the ability to separately configure everything related to its upper and lower border.
