The indicator implements a breakthrough system using the Color_QEMA_Envelopes_Digit channel.

When price exits the gray channel, the candlestick color changes to the color corresponding to trend direction. Blue is used for the growth of a financial asset, pink color means fall. Bright colors denote coincidence of trend direction and direction of a candlestick. Dark colors correspond to the situation when the direction of a candlestick is opposite to trend.

The indicator uses the SmoothAlgorithms.mqh library classes (copy it to <terminal_data_folder>\MQL5\Include). The detailed description of the classes is available in the article Averaging Price Series for Intermediate Calculations Without Using Additional Buffers.
