GBP/USD has fallen during the session as the "risk off" trade comes back into the fold. The cable is always sensitive to risk, and as a result it will fall when the stock markets do. The US GDP is being downgraded a bit by some analysts, and this will be poor for global risk appetite.
The USD/CAD pair reversed its course during the session as a result as well, and now the 1.03 level is being tested. The 1.02 area looks very supportive at this point, and as a result we are buying this pair on a break of the session highs.
