The Harmonic Pattern Indicator for the ATAS platform is a technical analysis tool designed to identify key harmonic formations such as the Gartley and Butterfly patterns. These patterns are based on Fibonacci ratios and can help structure market behavior across futures, crypto, and other markets. Pattern appearance depends on market conditions and may not occur on all timeframes.
Harmonic patterns are geometric structures built from five key points: X, A, B, C, and D. The final point, D, often represents a potential reversal area. Patterns like the Gartley and Butterfly are commonly used to frame price movement, consisting of an impulse leg, a corrective move, and a possible continuation or reversal.
In addition to harmonic structure recognition, the indicator includes unique order flow elements that add an analytical edge:
On the chart, the indicator dynamically connects pattern points from X to D as formations develop. Switching between Compact and Extended modes adjusts the pattern length, and enabling the Post-D filter narrows focus to relevant follow-through scenarios. Combined with order flow metrics like delta and volume, this tool enhances the structural view of market behavior.
This indicator is part of the JSI Indicators Pack for the ATAS platform and serves as a structured analytical tool. By combining harmonic detection with order flow context, it provides traders with an additional lens through which to observe price action.
