CHS Zig Zag

CHS ZigZag stands for Changeable Source ZigZag
The original ZigZag indicator offered by TradingView doesn't have the ability to measure the tips and troughs based on closing prices (line chart), however, this indicator is capable of receiving an input from user that determines the price source used for further calculations.
The default inputs of the original ZigZag indicator have been also changed in order to make it adapt to pivots formed on line chart but users can change arbitrarily.
