Relative Volatility Index Formula and Calculations
Calculate the standard deviation of the 'up' and 'down' days over the chosen period. Divide the standard deviation of 'up' periods by the standard deviation of 'down' periods, then multiply by 100 to get the RVI .

Относительная летучесть — это мера сравнения давлений паров компонентов в жидкой смеси химических веществ. Эта величина широко используется при проектировании крупных промышленных процессов дистилляции. Википедия (Английский язык)
Relative volatility is a measure comparing the vapor pressures of the components in a liquid mixture of chemicals. This quantity is widely used in designing ... |
Strictly, the relative volatility is the ratio of K factors for the components, where for each component, i, Ki = yi/xi. For ideal components, K1/K2 = P1/P2. |
This relation enables the composition of the vapour to be calculated for any desired value of x, if α is known. For separation to be achieved, α must not ... |
The RVI is a volatility indicator that helps traders identify the direction of price volatility. It ranges from 0 to 100, with values above 50 indicating an ... |
18 июн. 2022 г. · The relative volatility is defined as the ratio of K factors for the components, where Ki = yi/xi for each component. K1/K2 = P1/P2 for perfect ... |
Relative volatility changes with temperature but one value only is required for the next section. That value is normally decided by averaging the relative ... |
