If we have to give our thoughts. Here are mine. My trading system has a sell for the NDX alone. SPX and OEX are overbought but no signal. We just broke out of a Small triangle and a large triangle. Also a multiyear trendline on the Monthly charts. Today and yesterday, we had increasing volumes, althought not enought to say that it's impressive but it's getting there. So I am giving this sell signal less weight than usual and hoping for an intraday sell only. We may go down 20 points during the day, but hopefully it will come back to close about evens with todays close.
