GBPUSD failed a rebound opportunity in the weekly demand zone. Therefore, there is a 4 hour supply zone and a daily supply zone on the top, so the downward pressure is very large. In particular, since the daily supply zone is a location where a daily downtrend can follow, if it cannot break through this zone, it may come down toward the bottom. Conversely, if this line turns into a support line, the market can again test the blue line in the middle of the chart. However, this line has also turned into a very strong resistance line, which could lead to a decline if a breakout fails.
