BTC still down

So this simple method of using two indicators
the first is linear regression , the other is obv macd can be found here pastebin.com/hNyytwEbe
as we see the BTC is not able to break the decending channel of the linear and the no lag macd confirm downfall
this is where i normaly short it (best was around 9400 at indicator alert of macd)
I just put this short tutorial to show easy way to analyse stuff
the question is where it will fall ?
here i use support level like pivot (not shown in illustration to determine the low
8700 seems like a good target
if fall to 8000 then the bull run is over and we may see btc to fall much further later
but from my experience I expect to buy again at 8600-8700 which are good old support level
