If you sell, place your order "All Or Nothing" here's why
For the past 3 trading days, there have been hundreds of thousands of 100 share purchases. Each 100 share purchase is about 300 bucks in cash. Now, if you are trying to buy 10,000 shares, and are an individual, you pay 9.99 for each buy....only one type of investor buys 100 share blocks - large institutions.
Place your order at AON (all or nothing)...if you let them acquire the stock in 100share blocks, it will keep the price lower. Each volume uptick has caused a spike (like clockwork) to the 3.10 range.
