Rationale: AUDCHF's steep decline seems to have petered out in two ABCD patterns with failed CD legs. A bullish AB rally followed, which could yield CD follow-through taking AUDCHF across the blue ML, back into it's preferred upper half of the better-validated blue fork, to sliding parallel resistance or beyond.
