The EUR/GBP pair is trading in a symmetrical triangle pattern on a 4 hour time frame. These triangles usually break in the direction of the trend and on this time frame the trend is towards the upside for two reasons. Firstly, tit is trading above the upward trend line and as long as the price stays above this trend line, the bias remains towards the upside. Finally, the price is also trading above the 50 and 100 day moving averages (shown in yellow and red respectively). Moreover, this confirms that the bulls are in strong control of the price and their control will remain firm as long as we above these averages.
The RSI is trading in line with the price action which confirms that the upward price movement has a momentum behind it.
