When to Enter

NEW: Now since we got what we wanted the question would be when to enter. I would suggest on a pull back to 1520 around. For target of 1550/1570/1600.
OLD: This is great buy above 1536 with a confirmation. Probably between 1536-1540 for unknown upside. As price is near its lifetime high. Before that it might breath between channel of 1534-1508.
