distance from high

The Pullback Indicator defines how much a stock has retraced off of its low or high (depending on if it's an up day or down day). The retracement is expressed in terms of a percent of the stock's total movement for the day. So if it opens at 9.75, reaches a high at 10, then a low at 9, before climbing back up to 9.50 to close, then the retracement off the low of $0.50 is 1/2 the daily range of $1, or a 50% pullback from the extreme of the move (a reading of .5 on the indicator). The reverse would be true if it were an up day: the retracement would be the percent of the daily range that it has pulled back from the high, which on an up day is considered the extreme of the move.
