Expo Holdings Inc. (EXPH)

[Bentos]

Lets say that i bought expo in June, July and August and i ned to sell a small portion. Do any of those brokers that you recomend (scotrade does not) allow me to see which shares I'm selling online? I ask this becaused i prefer to sell the most recent ones (from august)since I'm long and want to get a better tax rate when i sell, and that means holding for a year. does this make sense or I'm getting something wrong? Thank you.
