This screen finds an upward breakout through a level 3 TD supply line, a falling line through the two most recent TD point highs with three bars on each side. Thomas DeMark draws TD lines objectively through the two most recent TD points, highs or lows with lower highs or higher lows on each side; the level, or magnitude, is the number of bars on each side. A close above the supply line signals that the decline may be over; higher magnitudes give fewer but more significant lines.
