Sell @ 0.6834, SL: 0.6895 (previously high). I will double my position if the price goes crazy and reaches above 0.6860. See there is a strong resistance from 0.6865 to 0.6895.
Target: 0.6650/0.640. If the price cannot hold here, it will drop to 0.640 area quickly. If the price holds, it can be back to retest the minor resistance zone 0.6715/0.6720 before falling down again. Just watch closely.
Long Plan:
Buy @0.6373, SL: 0.6238 (previously low). Target 0.66142/0.6650.
