Wave (( b )) is in place at 1.4510. Wave ( a ) appears to be a 5 wave move. Expect a corrective pullback toward 1.4581 – 1.4602 from where the pair should turn higher toward 1.4770 to complete a 7 swing structure up from 1.4371 low.  Hourly cycles are positive so we don’t like selling the pair in proposed wave ( b ) pullback.
