GBP/USD Technical Analysis: Cable bulls unwilling to let the market drop below 1.2957 key support

• GBP/USD Bulls are challenging the main bear trend as they are trying to break above the 1.3050 key level. 
• GBP/USD bulls have created a bull channel and the 100-period simple moving average (SMA) is starting to break above the 200 SMA, which is another bullish clue. GBP/USD bulls are keeping the market supported above the 1.2957 July 19 swing low (key support). The RSI and MACD indicators are bullish. If bulls break above 1.3050 then 1.3200 becomes the next objective. 
• A bear breakout below 1.2800 would invalidate the bullish bias.
