CADCHF: How to Catch Bullish Wave?

CADCHF reached strong horizontal structure support on a daily.

on 4h the price steadily declines within a falling wedge pattern.

to catch a bullish wave I would focus your attention on 0.686 - 0.688 horizontal trading range.
4H candle close above that will be our signal to initiate long position.

goals:
0.6905
0.692

in case of 4H candle close below the range, setup will be invalid and the pair will most likely keep falling.
