The sp futures are still negative but I don't think it should be sold down here under 820 at this time of day. Perhaps a rally above 828 could be sold later. Nasdaq is holding on to a slightly more positve chart and traded into its buy zone earlier. Some days (too many) it's hard to pick better intra day levels than the daily Buy/Sell levels. Substantial moves in the earlier mentioned markets have traded as mentioned but with such high, short term volatility around the stock opening it was too difficult to post levels.
Still lots of time for something today...
