Potential Gap fill to take us down 20%

Price looks extended into resistance, after a huge gap up we saw a huge spike in volume.

Now it appears that the sell side volume is taking over as we have not had many green days since we got here and the MACD has given us our bearish crossover.

The weekly does not make make it look any better as we seem to have a confirmed Gravestone Doji on our weekly chart:
I believe we could see a huge drop in the coming days possibly to fill the gap below.
