RE: E: ST technical reasons.
I think many saw the same ST technical reason you did yesterday. However, this ripple effect from the overnight China meltdown would not have shown up in any chart. Till now, it was just something many had pointed out that could affect markets sometime in the future. Just didn't know it was going to be today! :o)
Thanks for the chart links. As you know, I look at similar data based on the NDX. Yesterdays pull back was not too convincing, from a NDX volume breadth point of view. Hence my ST bullish view. A impulse day like today will throw alot of price and volume indicators out of whack.
Sorry about your down day today. And long at EOD? "Fortune favors the bold". :o)
Good luck!
