HFT example of pattern interference:
Below is the gold chart from yesterday and the SPY chart of yesterday and today.
Note the labeling of a Leading Diagonal in gold (an impulse move down), then a correction, and a following sharp break. Then look at the SPY chart with a similar, and quite valid, pattern that was broken by HFT involvement. One could muse over whether today's activity was due to the market being held up yesterday to sell it. That is the power of their involment in the stock market. Both patterns, if trading using EW, would be required trades for you don't get to be subjective and pick and chose what is a well laid-out trade for you don't know which one will be extremely correct. A Leading Diagonal could be an
A wave (making fair profits) or a
wave 1 followed by a powerful
wave 3 ( a massive profit). When you have a trading methodology and have found what you consider an "edge", you have to take the trade - every trade. Not taking it and watching it work is literally psychologically damaging to your confidence.

http://www.nanex.net/Research/QuoteStuf ... anned.html and look at the NYSE information that is petitioning the SEC to require quotes entered to have a minimum time to remain as a standing order. The market will trade more freely with less occurrences of 4.8 million quotes and 21 trades, which was the largest winning of
"Stuff the Machines" contest on Wednesdays.
See the end of Wednesday's post for some hard numbers on quote stuffing. It is FAR more invasive than I could have believed.
