deviating from the mean price. Higher the standard deviation, greater is the volality. In the first step, we calculate the mean and standard deviation of the recent VAR_PERIOD candles. In the next step, we calculate the variance by subtracting the price from the standard deviation. Finally, we smooth the variance, using the co-efficient, which is reciprocal of (1 + VAR_PERIOD). When the variance increases, the probabilty of fast./,
