ICT/SMC Strategy on GBP/USD H4

GBP/USD is in a downtrend on the higher timeframes,Yet we only looking for sells,I have identified a HTF(Higher TimeFrame)Supply I would like to see how price reacts at that specific level.Once I see some confirmation such as Liquidity Grabs Considers trading Short on GBP/USD.I also see a potential BOS Which may be a correction to the downside once retest.
