Your post did not make any sense, until I realized that you must not have realized that my post was in reply to message #14335, which if you read, then the comment should make sense to you.
Unfortunately, I have bought more than 10,000 shares of CBAY at once. My last buy was for over 30 times that much. That order was filled in two buys. I was charged commission one time. If you are getting charged separate commission on each segment of your order, perhaps you need a new broker.
