In the daily chart, GBP/USD is still trading sideways below the resistance zone of 1.5755. Moreover, the current structure remains strong and pointing to the upside because 200 SMA is bullish. There is a chance of another pullback towards that moving average. The MACD indicator remains in the negative territory.
The short-term picture is still dominated by sideways moves as the pair was rejected by the resistance level of 1.5740 during Tuesday's session. However, a breakout of the support around 1.5687 would open the doors to test the next low of 1.5650 in coming hours.
