GBP/USD Technical Analysis: Cable might run into bullish exhaustion below 1.3300 figure

• GBP/USD is in a bull trend as the market is trading above the 50, 100 and 200-period simple moving average. 
• GBP/USD broke above the 1.3200 figure as it is nearing the 1.3300 (September 20 swing high). The Stochastic indicator is in overbought condition suggesting that the bull run might be exhausting itself. However, there is no sign of a top yet and the market might potentially spike to 1.3300 figure in the meanwhile.
• A bear breakout below 1.3100 would likely invalidate the bullish bias.
