Other indicators give leads but it is volume which gives stamp of approval to signal. Because of this reason various volume based indicators emerged and some of the prominent ones are Chaikin Money Flow(CMF), On Balance Volume(OBV), ADL and Money Flow Index(MFI).

Money Flow Index was developed to gauge buying and selling pressure. It is yet again a momentum oscillator that takes with price and volume in consideration.
