Welcome

Trading Defenders is a site devoted to protecting the stock trading industry.  It is important that we educate the general investing public of the need for traders, and the importance of having traders in the marketplace. 

Trading Defenders strives to educate other traders and investors about structural changes in the market, and how we can deal with these changes.  We are currently defending traders against abusive trading practices such as sub-pennying, and flash trading.  These practices create a two-tiered market system. Trading Defenders seeks a level playing field for all traders.

Trading Defenders is NOT opposed to high frequency or algorithmic trading.  We are opposed to abusive strategies that compromise the integrity of our financial markets.

Be sure to visit our new site, where we help you navigate in this HFT world:  www.premarketinfo.com
