What I expect is a pullback to $600 through 9/15.
Now that price has popped up quickly it is still not a sign of long term bullishness. In fact, the move was too sharp to be indicative of a real sustained trend to turn the Daily into territory. Price is still below the cloud and fighting it due to this move.
Interestingly enough, 9/15 falls on a Thursday before the "Bullish Friday" statistic. At that point I expect it to battle where the 26 period Kijun Sen will be at the nice round number of $600. That will be our Daily support. Depending on if price holds it or breaks it will be the cadence for the next several weeks. If it breaks it I expect price will also break the lows and start moving down to sub-$500. If it holds then there is a chance to consolidate bullishly and maybe return price to the upside.
Bitfinex versus Bitstamp
Unfortunately for the next several weeks the of BFX and BStamp will be different. The weekly will not match for perhaps 6 months. I have to pick one so I'm going to be referring to BFX charts for two reasons. 1) Traders can open short margin positions there and 2) still drives much of the of BTCUSD trading.
