The following commentary comes from an independent investor or market observer as part of TheStreet's guest contributor program, which is separate from the company's news coverage.NEW YORK ( TheLFB-Forex) -- As equity indices test the break-even point for 2011 ahead of a week of political and banking jawboning, a certain reality is forming for many in regard to trading expectancy and subsequent follow-through. The realization that the main participants in the stock market arena are high-frequency trading (HFT) algorithms will come as no surprise to most, and love them or loathe them, HFTs are in control. The question from Main Street now is not about who is in control, but whether Wall Street can deliver in the new environment. The mass exodus from equity managed funds over the last 24 months suggests confidence in the pros may not be running high. The increase in managed futures trading looks to be in part a result of the shift from buy and hold towards buy and sell.
