The inertia indicator measures the market, stock or currency pair momentum and trend by measuring the security smoothed RVI (Relative Volatility Index). The RVI is a technical indicator that estimates the general direction of the volatility of an asset. The inertia indicator returns a value that is comprised between 0 and 100. Positive inertia occurs when the indicator value is higher than 50. As long as the inertia value is above 50, the long-term trend of the security is up. The inertia is negative when its value is lower than 50, in this case the long-term trend is down and should stay down if the inertia stays below 50.
