GBP/USD went on an upside run to the 1.6140 high this morning, but now is back to the 1.6000 level. Intraday bias remains on the downside, as long as the 1.6440 minor resistance line is not broken. On the upside, if the 1.6440 minor resistance line is broken it will change the bearish bias to bullish sentiment and target the 1.6545 major resistance line.
