Traders often wait for confirmation of these patterns before entering a trade. For a double top, confirmation is obtained when the price breaks below the neckline, which is drawn by connecting the lows between the two peaks. Conversely, for a double bottom, confirmation is obtained when the price breaks above the neckline, which is drawn by connecting the highs between the two bottoms. The profit targets for these patterns are determined by measuring the distance between the neckline and the highest/lowest point of the pattern and projecting it in the direction of the breakout.
