15M Wave count shows pull back in last leg up

EURUSD on the 15M chart looks to be doing a double corrective structure to the upside. So far we have already completed wave W and Wave X. In Wave Y we have done the first leg up, and pulling back to completed Wave B. Expecting Wave X @1.0921 to hold for this view to remain valid.
Looking to buy for a move to 1.1050 (refer to 4H view).
