How to trade ABCD Harmonic Pattern

The AB=CD or ‘lightning bolt pattern‘ Harmonic Pattern

AB=CD is a reversal pattern that helps you identify when the price is about to change direction
AB=CD pattern is a four point harmonic pattern which may be considered the developmental basis for other harmonic patterns.
A-B leg when a market is trending upwards, the first leg (A-B) is formed as the price rises/fall from A to B.
B-C leg price switches direction and retraces up/down between 38.2%-78.6% to form the B-C leg.
C-D leg At point C, the price switches direction again and continues its original uptrend. This leg (C-D) slopes upwards, parallel with the A-B leg and should ideally be the same length as the A-B leg when it completes.

The ideal AB=CD pattern is equal in time and price, with point D being an Fibonacci extension between 127%-161.8% of the B-C leg.

You can sell at point D (or just before) where the pattern ends, or, in a downtrending market, go long at point D.
A perfect (hence highly reliable) AB=CD harmonic pattern would have an A-B retracement with a market price differential multiplier of 0.618 and a B-C projection with a market price differential multiplier of 1.618.

Your entry would be to buy or sell the area where AB=CD
Your stop loss would be above /below D. Meaning below the high or low that is D.
For targets, I use 38.2%,50% as Minimal Target and 61.8% of CD leg as Ultimate target .
Watch closely how the price reacts around the levels. If the price struggles to break through any one of them, then you can close your trade down and take profit early.
For trailing your stop, you can raise it to a breakeven as soon as the minimal target is achieved
