Bullish engulfing -The GBP/USD pair holds on to gains ahead of the Asian opening, but the upward potential seems well limited according to technical readings in the 4 hours chart, as the rally stalled well below a mild bearish 200 EMA, although above a directionless 20 SMA, while technical indicators entered positive ground before losing directional strength. Given the Brexit situation, the upward potential for the Pound is quite limited, with spikes being taking as selling opportunities by speculative interest.
