Looks like Ascending Triangle correction is going on in wave 4 but wave D is not the longest (breaking Ascending Triangle rule that wave D should be longest but at the same time it is closest to Ascending Triangle formation than other three variation). If this is Ascending Triangle construction then wave E must retrace wave D by atleast 50% and end above wave C. This zone could be anything in below range:
1497.80 < Wave E end < 1675.25.
And after that ride impulse wave 5. Good luck with your trade!
