Following a daily upper Bollinger band crossover on Monday, the GBPUSD pair recorded modest losses yesterday and closed at 1.4157, after nudging a low at 1.4066. A potential signal line crossover from below by the 2H MACD, accompanied by the 8H RSI and stochastic indicators sharply heading towards the north, reflects at positive momentum in the coming session. In addition, the .daily momentum oscillators are trading at a higher level above their centerlines, further supporting the above stance. Key technical resistance is placed at the 1.4218/20 level, followed by the daily upper Bollinger band (currently trading at 1.4257/60) and the 1.4299/1.4300 level. A break and stability above the latter might lead to upside momentum in the pair. On the other hand, crucial support is seen at the 1.4160 level, followed by the 8H 20SMA (currently placed at 1.4128/25) and the 4H 50SMA (currently trading at 1.4092/90). A breach below the later might trigger further negativity in the pair.
