It’s all of that and more. There was literally a breakdown in the trading system for over five minutes. I was watching it and suddenly the DJIA was down over 900 points at one point, if I recall correctly. The drop happened very suddenly from 10471 to 9873 in less than ten minutes, based on my 5-minute chart that I’m looking at from my chart service. That’s a drop of 598 points in less than ten minutes to the low of the day. That’s a breakdown in the trading system...not good for investor confidence.
You are correct in your timing.
I saw -450 or so, got up to tell a friend. He was on the phone, so I walked by to my desk and it was around -600. Two minutes later -830.
Went back to his desk and google finance was frozen.
Would that mean a massive move on short sales using the Breakdown Trading System?
