EurUsd long

I am pursuing the basic scenario of eurusd going down, but there is an alternative option that the whole impulse down has ended with an ending diagonal in wave 5. This analysis is not unique, a lot of wave traders are showing it.
What do we have at the moment:
1. Impulse as marked on the m15 chart
2. Potential three-wave pullback unfolding and close to its completion
3. Price at the reasonable depth for the pullback for the wave 2, if the scenario works out as we assume.
Today is the right time to buy. I am in already
