GBP/USD Technical Analysis: Cable bulls eyeing 1.3050 last bearish bastion

• GBP/USD main bear trend is on hold since mid-August.
• The 50-period simple moving average (SMA) broke above the 100 SMA which are both slightly ticking upward while the RSI, MACD and Stochastics indicators are bullishly configured.
• The next resistance to overcome is 1.2957 after which 1.3050 become the next bastion for sellers to defend the bear trend. A bear breakout below 1.2800 (August 24 swing low) would invalidate the bullish bias.
