Fears of a no-deal Brexit and a stronger dollar weighed the pound yesterday.
The main scenario is a bullish extension towards the area of 1.2360.
An alternative scenario is a corrective slide to the 1.2220 support.
Buy the sterling towards 1.2360 when the GBP/USD pair overcomes 1.2320.
A sharp breakout below 1.2270 could spark a further fall 1.2220.
