Despite intra-day resumption of the decline from last week's record high at 1.5905, loss of downward momentum should prevent steep fall below 1.5341 and reckon 1.5300/10 would limit downside, yield a corrective rebound.  
On the upside, above 1.5430/40 would bring retracement towards 1.5473 (Friday's high) before prospect of another fall later this week.
