Harmonic Pattern Indicators for cTrader

A harmonic pattern is a five-point structure labelled X, A, B, C and D whose legs must fit set Fibonacci ratio ranges. Gartley, Bat, Butterfly and Crab differ in those ratios, and an indicator flags completion near D as a potential reversal zone.

They suit people already comfortable with swings and Fibonacci ratios, because judging whether a detected pattern is clean takes experience. Beginners can still use them to learn the shapes, but a scanner that labels many patterns quickly can encourage overtrading, and every pattern can fail.

Many watch the zone around point D for a reaction rather than treating it as an automatic entry, and wait for confirmation such as a rejection candle. Invalidation usually lies beyond the zone, and targets are often measured as retracements of the final CD leg.

They are applied mostly to forex pairs, gold and crypto such as BTCUSD, often on H1 and higher, where swings are clearer than on minute charts. In the Windows or Mac app, attach the scanner to a chart and check its settings for which patterns, symbols and timeframes it watches.

Point D is provisional until price turns, so if the move keeps extending past the ratio range the tool may redraw or delete the pattern. Detection also depends on swing-size and ratio-tolerance settings, so two tools can show different patterns on one chart, and history may look more accurate than live use.
