possible bullish ABCD pattern GBP/AUD

A break and close below 1.98307 on the 4 hour chart could lead to the D completion leg of a bullish ABCD pattern on GBP/AUD. look for reversal between 1.96631 - 1.94527. For me to take this pattern I would need the deeper move to the 1.618 extension into the support zone by the trend line before considering a long position.
