GBPUSD tends to decrease when it hits resistance

On Wednesday, the GBPUSD fell sharply during the European session as UK inflation for November came in below expectations. The fresh weakness is expected to completely reverse Tuesday's gains and challenge key support at 1.2636. With the overall decline of the GBPUSD, bears are expected to test the starting point of the upward impulse waves. Subsequently, the bullish bias will still exist to keep the structure of "upward impulse waves" intact.
But the focus is now on the downside. As the Relative Strength Index in the 4H timeframe fell below 50 and below the lower limit of the long-term rising regression channel, reflecting a shift in the technical outlook to bearish.
On the downside, the 1.2600 level is now the first support level for the bullish market. A 4-hour close below this level could open the door to a further slide towards the 1.2550 level. It is recommended to go short at the highs.
