GBPUSD About to drop in the EU opening market

With my indicators, i can clearly see that the GBPUSD will reach the bottom of its 1H descending channel + i published that DXY is about to reach the daily resistance in a close timeframe, so GBPUSD has to go down also. Wait little bit if he's doing a fake 15 min range breakout by the top and catch it with your short at the best price.
I opened my position already at 1.3772,
TP 1.3735 (37 pips)
SL 1.3800 (28 pips)
I'm risking 5% of my capital but i feel really confident on this analysis, what about you guys ? Will you follow my idea ?
