180908 When to close my short position?

I warned you guys that it will start free falling soon and I went into short position, in my last comment of previous eng posting.
I am still holding my short position from $7,374 (XBTU18), and repeating short term long position scalping as a hedge. (XBTUSD)

Now I have to set optimal closing strategy to maximize my profit.


Now I can see a diamond pattern, and every indicator shows it will go up to at least $6,600


So for now, I will keep trying to find a good spot to scalping long position.

Maybe I can put some more short order if it spikes up to $6,800.
However If it break up to $7,000 again, than I will give up and take some small profit.
