GBPUSD finds no support at pivot point

GBPUSD has been falling and just completed a bear flag as shown on my 4 hr chart - I see no strength on the weekly and a denial of a critical support pivot point at the bar flag
This .pair could possibly fall as low as 1.35 as it looks for major support before a serious reversal and weekly stoch rsi cross over of strength.
I will be looking to enter this trade with my #forex trading students and will help them manage the trade along the way with specifics of position and stop loss management
