Quote from NY0BScalper:
Lescor is right. $5k/month is nothing... $5k for 4 months into the year means barely making any moves. Not sure what my YTD comm is but probably don't want to know.
Well, it totally depends on what type of trader you are... if you are a swing trader, perhaps you have a decent or good edge in that you only need a trade every few days, which would only be, say, 50$ per week, or 200$ per month, or 1000$

But of course when you start being forced to break orders up so as not to shock the market, or trading premarket, or routing fees, or whatnot, then yes, that 5K isn't much at all.
What also matters, of course, is your edge. Perhaps you have such a great trading edge, that you only need a couple of trades to make a killing... in that case, you wouldn't have much of a bill in commissions anyway.
I think one way to tell the size of your edge is based on a few bits of data
1) Account size
2) Profit$ (Percent%) this year
3) Commissions $ (Percent of profit$).
