On Balance Volume
The On Balance Volume Index ( OBI ) is a cumulative momentum style indicator which which ties together Volume with price action. The Underlying premise behind this indicator is that 'informed' investors take their positions prior to an extended move.

If Close is Higher : Yesterdays OBI + Today's Volume
If Close is Lower  : Yesterdays OBI + Yesterdays Volume
If Close is Equal   : Yesterdays OBI

There are a number of methods of using this very useful indicator. As shown above, divergence can be used, also as the OBI being a cumulative indicator, you can also look for higher highs and lower lows as confirmation of a trend. Finally, you can also watch for OBI movement occurring prior to the underlying market. Should this occur, this can be read as 'informed' money taking positions prior to the general public.
