GBP/USD Technical Analysis: Cable bulls giving up nothing, holding on tight above 1.2900 figure

• GBP/USD bears are eager to push the market below 1.2900 psychological level in order to resume the main bear trend. However, GBP/USD is evolving in a bull channel above the 50, 100 and 200-period simple moving averages. The RSI, MACD and Stochastics are constructive to the upside. 
• The key levels to break for bull are 1.2957 (July 19 swing low) and 1.3050 (August 30 swing high)
• A bear breakout below 1.2800 would invalidate the short-term bullish bias.
