i dont use all those nonsense indicators that a few other people mentioned.. LD
Just stick to looking at the chart in 'line-chart' view, seeing where the really strong S&R levels are on the daily/monthly chart,
then wait for huge elongated moves to exhaust themselves before then attacking into them for the snap-back.
Dow is near string resistance around 8926 level,
so i got my sell in at 8906.
i see next support not till 8637, but as i have to cash this trade in before todays close i see likely low support today of around 8786.
(we just need some bad home sales and unemployment claims and then this piece of crap crashes)
