Valeria Bednarik, FXstreet.com collaborator, comments: Gbp fall has halted, yet pair consolidating around lows, suggest the upside will remain limited during next trading hours. Indicators had already corrected the oversold state in the hourly, while 20 SMA has turned quite bearish both in 1 and 4 hours charts, suggesting more downside to come. Under today's low, watch the key 1.6340 area as a break could accelerate selling momentum. Only above 1.6440 pair could reverse current bearish bias.

Bednarik provides us with her levels: Support levels: 1.6340 1.6300 1.6250. Resistance levels: 1.6410 1.6440 1.6485.
