Tom,
I personally am not that fond of them in most instances and would
rather just use the 0 to 100 scale but there in is the problem. The
theory is that by using a bipolar index you can swing much farther
out of the boundaries of the 0-100 scale. Have you ever noticed how
an indicator will shoot to the extremes of the overbought/oversold
side and then flatline? The bipolar in supposed to overcome that.
