Election headlines and Brexit optimism are pushing the pound upwards. Besides, geopolitical tensions between the US and China capped the dollar's advance. The Cable still has room for extra gains.
The main scenario assumes a growth of negative sentiments and a return to the 1.2890-1.2880 region.
An alternative scenario is a growth to the 1.3010 level.
You can sell the Cable to the 1.2890-1.2880 region when the rate breaks 1.2940 and stays below it.
If bulls retain control and overcome 1.2950, buy the GBP/USD pair towards 1.3010.
