Cabbie, i take no credit there; merely admire Mittas work.
OBV ... tell us more on how you use it. I am all ears. just checked theory "On Balance Volume
In 1963, Joe Granville developed On Balance Volume (OBV), which was one of the earliest and most popular indicators to measure positive and negative volume flow.

OBV uses the change in closing price from one interval to the next to value the volume as positive or negative. It does this by maintaining a moving cumulative total volume figure, which is adjusted by either adding the current intervals' volume to the cumulative amount if the interval closes higher than previously, or by subtracting the current volume from the cumulative amount if the interval closes lower."

and Using the OBV
"In normal circumstances the OBV line will tend to track the price chart, and a trend line drawn on the price chart will appear similar when drawn between the same dates on the OBV chart.

However, when the OBV line fails to move in the same general direction as the price chart, it is an indication that a price divergence may exist. This may result in a trend reversal."
