The pair is facing a dynamic resistance in the 200 SMA at H1 chart and it's again on the way to test the support level of 1.3037, which adds strength to the bias proposed. If that zone gives up, then we might expect a leg lower towards the 1.2880 level, but if it manages to do a rebound then it can break the resistance area of 1.3201.
H1 chart's resistance levels: 1.3201 / 1.3309
