Long Setup based on PA

FX:GBPUSD   British Pound / U.S. Dollar
Price Action Trading. Specifically using Liquidity Gaps to trade around. If there is close above previous high, a long setup to the 4h LG above would be an ideal trade with good R/R.
Comment: So this trade didn't go to plan. This is because there was a 30 minute Liquidity Gap (LG) below the 4h LG. So what has happen is price has reacted off the 30m LG above and moved back down. There reason for my TP being on the 4hr LG is because the RR would be good, however if it was at the 30m LG then the RR would have been very low (1:1.5)
