The beginning of a pullback?

I've been watching this ETF for a while, always trying to buy at the exact point but couldn't just because I was afraid that it would go down just before I buy. Since November is been acting with divergence with its RSI so I waited, and now I think the pullback just begun so I'll keep waiting but more active. I like to buy when the price tests its MAs, especially the 20 day MA. This time I think it could test the 50 day MA but anything can happen so the best thing is always wait and be patient, but I'll put a signal on $48 to wait actively.
