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.
