GBP/USD Technical Analysis: Have Cable bulls ran out of steam after 400-pip run-up?

• GBP/USD is trading in a bull trend above the 200-period simple moving average on the 4-hour chart.  
• GBP/USD has enjoyed a significant 400-pip bull run in the last days of trading. Bulls are trying to break above the 1.3100 figure this Tuesday but found resistance. Bulls might try to give another try at the 1.3100 level later in the New York session but if bulls fail twice at this level that doesn’t bode well for them as a pullback to 1.3043  could be in the making.
• The RSI, MACD and Stochastic indicators suggest a somewhat overbought market with limited upside potential.
