can I interpret that as a potential fast short decision?

i'm trying to focus on short trades for the moment; i just begin trading bitcoin for fun; i'd love to have some feedback. I don't know if I can abuse of "ideas" to ask questions; tell me if I can i would happily post more spot i don't understand. I think I have a problem for time scale management too; i'll try to work on that.

I read that as a potential fast profit short order and would setup my target around 391.

My two others questions coming for that order are:

- how do i enter? should I do a stop sell or limit/market?
- considering the volatility how should I setup my stop loss.

Thanks a lot
