For the Nasdaq the right-hand-shoulder may be viewed as a traditional double bottom reaction low (with a neckline around 1,675). The early October double bottom was violated by the break to new lows in late October.
Should the S&P violate 900 as support by the close of business then the next target is the October reaction low of 850. Irrespective of 900/850 support the neckline at 1,000 would remain the confirmation level to a bottom. Technicals are mixed with a bullish 'buy' in Money Flow but a bearish 'sell' for stochastics.
A closing break of 850 means the downtrend resumes and the bottoming process is reset to zero.
