Coming soonThe Marney Volume Indicator (MVI) is used to plot a time-adjusted profile of volume throughout the 24-hour trading day. The MVI takes the true range of each hour of the day over a preceding number of days and plots that value as a time-adjusted average. <br>''Developed by Caspar Marney.''<br><br>The indicator takes each hour of the day (for example, 8:00 to 9:00 a.m.) and then calculates the average volume for that hour over the past N days. Thus it gives you a measurement of whether the current volume is larger or smaller than is typical for that specific time period. <br>
