GBP/USD Technical Analysis: Is there fuel left in the bear tank?

• GBP/USD is trading in a bear trend below the 200-period simple moving average on the 4-hour chart. 
• GBP/USD had a sharp pullback up this Wednesday piercing 1.2800 on an intraday basis but unable to keep prices above the level. Bulls would need a break of 1.2800 on a daily closing basis in order to gather some strength after the October selloff. 
• The RSI and Stochastic indicators are below the 50 line while the MACD has crossed over from below the midline. All suggesting that a potential reversal up can be in the making on a break above 1.2800 figure in the coming sessions. On the flip side, failures at 1.2800 will keep the bearish bias intact.
