The GBP/USD pair is trading in a resistance zone on 30 minute time frame. The price has pierced the Bollinger band at this level and it is trading above its 20-day moving average. The piercing of the Bollinger band does have a significant importance when this occurs at an important level of support or resistance. In this scenario, the GBP/USD has pierced the Bollinger band at an important level of resistance and thus it could reverse the trend or bring a temporary pause in this upward trend.
The price is trading above the 50 day (shown in green) and the 100-day (shown in yellow) moving averages which means that the bulls are fully in control. Moreover, the price has failed to break the upward trend line which further strengthens this argument.
The RSI is trading in line with the price action which means that the bias could be to the upside.
