Anticipating a quaisomodo pattern [GBPCAD]

Anticipating a move down to retrace the up move from two weeks ago. Has been in containment for ~a month. After the full retracement I am anticipating a move back up to test the previous supports turned resistance, and then ultimately move lower than the low that brought us to the up move from two weeks ago. This move may happen around London open.GBPCAD

My idea falls through if we manage to break 1.71 on open.
