A simple indicator that calculates rounded volatility of a financial asset. Volatility is calculated in points based on the maximum and minimum prices of smoothed Heiken_Ashi candlesticks.

Volatility is calculated as High minus Low of Heiken_Ashi_Smoothed candlesticks. The resulting value is converted into points and rounded according to the coordinate grid step defined by the StartLevel and LevelsStep input values.

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".
