StockTwits, Inc.

Here is a very good explanation…..

High frequency traders have the abitliy to spoof the stock market especially in high volume marketplaces like SP500 futures, eurodollar, bond futures,and some forex.Although, you need to have the technology, a trader has to be very astute and have a quick eye to spot certain entries to execute quickly and swiftly. The way I see it, high frequency trading has its pros and cons, its a two-way street in the open free market environment. Obviously, retail investors/traders have the low end of the stick, but if you can see and read the right patterns in any given time frame it would be a great catalyst to virtually any level of skill a trader has but with the right mindset.
