Harmonic trading is based on the premise that patterns repeat themselves and the symmetry can be exploited to define the geometric and harmonic relationships between price and time-swings using Fibonacci ratios. Harmonic price movements produce symmetric rallies and decline to give traders an advantage to determine thekey turning points (pivots) and well defined and repeatable chart patterns. One of the simplest and most universal chart patterns is ABC Chart pattern. Please see "Trading ABC Chart patterns" with a bullish ABC pattern example in December 2016 Modern Trader magazine. Here I will discuss ABC Bearish chart pattern with a recent example.
