GBP/USD Technical Analysis: Target at 1.2838 mission accomplished - What is next after rising wedge?

• GBP/USD main bear trend is on hold for the fifth consecutive day as the market is having a bullish pullback.
• GBP/USD had a spike breaking above the bullish channel in a rising wedge shape, suggesting that the market went too far too fast. The correction might extend near 1.2789-1.2800 support coinciding with the 50% Fibonacci retracement of the last bull leg from Monday. 
• If the market reaches 1.2789-1.2800 support, traders will be watching the market reaction in order to decide if the short-term bullish momentum is still in place.
