Mastering the Ending Diagonal Pattern: A Guide for Traders
The ending diagonal is a distinctive pattern in Elliott Wave Theory, often signaling the conclusion of a strong price movement. Recognizing this pattern can provide traders with valuable insights into potential market reversals.
What is an Ending Diagonal?
An ending diagonal is a specific type of motive wave that appears in the fifth wave of an impulse or the C wave of a corrective pattern. It typically forms a wedge shape, indicating a slowdown in the prevailing trend and a possible reversal.
Key Rules of the Ending Diagonal
Wave Structure: The pattern consists of five waves, each subdividing into three smaller waves, following a 3-3-3-3-3 structure.
Wave Overlap: Waves 1 and 4 often overlap in price territory, a feature uncommon in standard impulse waves.
Wave Lengths: Wave 3 cannot be the shortest among waves 1, 3, and Trendlines: The pattern is bounded by two converging trendlines, forming a wedge shape.
Throw-Over: Wave 5 may extend beyond the trendline formed by waves 1 and 3, known as a “throw-over,” often followed by a sharp reversal.

Examples of Ending Diagonal Patterns

Trading the Ending Diagonal
Entry Point: Consider entering a trade when wave 5 completes, especially if accompanied by a throw-over and divergence in momentum indicators
Stop-Loss: Place stop-loss orders beyond the extremity of wave 5 to manage risk.
Profit Target: Aim for a retracement to the start of the diagonal pattern, as prices often return to this level after completion.
Understanding and identifying the ending diagonal pattern can be a powerful tool in a trader’s arsenal, offering early signals of potential market reversals. By adhering to its defining rules and analyzing real-world examples, traders can enhance their market timing and decision-making strategies.
