this is a great question. makes me think anyway!! i must admit - part of me resents working for the broker, but as some have said, why bother about the brokers pay. our net is more important. it would be the same profit split if i was in a prop shop anyhow!!
i agree w/ Commission being part of the cost of doing business, the problem i see with overtrading is also exposing yourself to unnecessary risk, and maybe slippage also. i would think 1 to 1 is pretty high
It mostly depends on your time frame I'd think, a successful long term investor should have a much higher profit:commission ratio than a skalper. My own 7:1 ratio comes from a 2-5 day holding time. Any day traders care to comment?
