With a threat to its Tuesday rally now seen following a loss of upside momentum at the 0.8280 level, risk is now building towards a retarget of the 0.8172 level, its Aug 16'10 low. Below there will open the door for a run at the 0.8100 level, its psycho level. Alternatively, to reverse its present weakness and resume its recovery, the pair will have to break and hold above the 0.8280 level to create scope for a run at its July 22'10 high at 0.8464. On a further strength, its May 21'10 high at 0.8772 will be aimed at.
