A close cousin of the double top and double bottom are the M top and W bottom, so-called because of the letters formed when the thrust to a previous high or previous low does not reach the same level as the first high or low. The key that confirms a price reversal is a break above the interim high on the W bottom and a break below the interim low at the M top. The interim highs and lows can often be used to determine where to place entry or exit orders, depending on your market position going into the pattern.
