The trendless indicator (oscillator) is based on the book "Trading with DiNapoli Levels" by Joe DiNapoli and made as a colored histogram. Additionally, smoothing of the final indicator is performed.
The indicator uses SmoothAlgorithms.mqh library classes (copy it to <terminal_data_folder>\MQL5\Include). The use of the classes was thoroughly described in the article "Averaging Price Series for Intermediate Calculations Without Using Additional Buffers".
