I'm a scalper. For the first 7 years of my career, my commissions would be about 25% of my gross. If I grossed $2000., commissions would be about $500.
Now with this market, decimalization, and for whatever reasons, it's not uncommon for my commissions to be 50-100% of my gross. Make $2000. spend $1000 in commissions.
If it 50% or less, I feel like I didn't really overtrade. If it's more than 50%, I overtraded.
When the market has forceful meaningful moves, my commissions will usually be at the 25% mark. Other than that I'm just churning and burning most of the time. Trying to catch a few moves that will make the difference in my P&L.
It's been tough, no easy money, but, I'm still making a living.
I would love to trade in a way where I can avoid all of this noise in the market,(especially because of decimals). I'm always working on that, but, until I figure out a way, I have to stick with what I know.
