Hi Jim,..Re:.OBV,
You probably already know this but below is a link to the formula and description of OBV along with Dell daily and weekly charts showing OBV. <g>
mindspring.com Balance Volume
On Balance Volume relates volume to price change. It is calculated by adding the day's volume to a cumulative total when the security's price closes up, and subtracting the day's volume when the security's price closes down.
If today's close > yesterday's close,
then OBV = yesterday's OBV + today's volume
If today's close < yesterday's close,
then OBV = yesterday's OBV - today's volume
If today's close = yesterday's close,
then OBV = yesterday's OBV
On Balance Volume is a running total of volume. It seeks to show if volume is flowing into or out of a security. When the security closes higher than the previous close, all of the day's volume is considered up-volume. When the security closes lower than the previous close, all of the day's volume is considered down-volume.
The following formula calculates the On Balance Volume indicator: (if(c > ref(c,-1),1,-1) * volume) + PREV. Note that the PREV constant represents the value of the indicator on the previous day.
