GBP/USD - Potential long

2nd touch on a parallel channel. Also lines up with a very strong key level going back years (see screenshots below). However EMA's just crossed and is on a strong downtrend, so will be waiting for a strong confirmation of a reversal on a lower time frame. Daily 200 EMA is just below were price is now so is a good confluence for a buy compared to the 4h EMA's.
