ABCD Harmonic Pattern Signals from Fractal Swings

Summary

This script identifies potential ABCD price patterns by finding swing highs and lows with fractal rules, linking the pivots into a zigzag sequence, and comparing the relative lengths of its legs. It flags bullish and bearish setups when the retracement from A to B falls within a stated range and the C-to-D extension meets another stated range. The pattern direction is determined by whether the final pivot sits below or above the preceding one.

The document is an incomplete source excerpt rather than a full strategy explanation: it shows pattern construction, chart labels, and the beginning of later order logic, but cuts off before the entry and exit rules can be assessed. It gives no backtest settings, performance results, or discussion of risk controls. The visible script also uses a lookahead setting in its pattern function, which can affect historical signal timing and makes careful review of signal availability essential before evaluating the approach.

Key ideas

• Fractal rules are used to identify swing highs and lows for a zigzag pivot sequence.
• The ABCD setup is evaluated using ratios between successive pivot legs.
• Bullish and bearish labels depend on the location of the final pivot relative to the prior pivot.
• The excerpt ends before complete order rules or risk management can be reviewed.
• The lookahead setting may affect when historical pattern signals appear.
