AUDUSD Bearish Signal 2Hr TF

AUDUSD is in a downtrend after the bearish impulsive phase that broke the bearish flag. The price is presently at a major support level, i expect a break of this level, retest before I will possibly short it.

How ever, there is only one thing that could invalidate this trade, if the price reverses back from this support as marked with the red arrow , this would invalidate this trade setup.
