Description
The OnBalanceVolumeModified (OBVM) study is a technical indicator introduced by Vitali Apirine. It is a variation of OnBalanceVolume (OBV). In the modified version, OBV is given a smoothing (by an exponential moving average, by default). In addition, a signal line is introduced. The signal line is a slower moving average of the smoothed-out OBV.
When the main line of the OBVM is rising, the volume might be gaining positive pressure, which may further result in an increase of the price. Conversely, decreasing OBVM may signify decreasing volume pressure and a further price reduction.
The main line can also be analyzed in terms of divergences from the main price plot. The signal line can be used to identify crossovers.
