Hi, lwlee.....
you are right, I am a scalper. Everyone has to choose what fits them, and this fits my personality.
I don't concentrate too much on what I pay in commissions. WE all have to make a living. I look at my bottom line. If I have a dollar more (net net) today than I had yesterday, I am happy. And, if I have created a job for someone else in the process, that is great.
(PS: My commissions are extremely low, due to the volume I do every day)
Thanks again for your feedback.
