Quote from Lucias:
Yes, I've seen a pattern in the order flow. I call them "flurries". Its when the market moves up about 4-6 ticks, very quickly, and the immediately reverses and makes a run down. Happens too fast for me to take advantage of...
Never understood these claims and I got no responses in my other HFT ES thread. So how is this supposed to happen? ES is tracking the SPX. The SPX is tracking a basket of 500 stocks. The SPX and ES move in lock step, up to tiny noise at the few seconds timeframe. So HFT is supposed to push ES around? But ES tracks the 500 stock basket. The only way HFT could push ES around is if the institutions running HFT are simultaneously buying and selling hundreds of millions of shares of the S&P 500 stocks. Not sure if that is really happening.
