| NASDAQ 
 there are three big corrections for NASDAQ, two in 2012 and one in 2014.
 all three touched the lower BB and bounced back.
 
 besides there are a few small corrections touching middle line, but that 's it.
 so my conclusion is we won't have a back-to-back big correction in nasdaq,only small ones, although tech has been crazy these days.
