For every trader there is, there is another trader that is completely different. One may be very experienced at counter-trend and another very good at trend. One is a Scalper and other go for much bigger plays. You really asked an impossible question. Also, you have retail traders doing a one lot and other traders that might have a staff of twenty or they have remote traders trading for them, automation of one to fifty systems and either lease or buy seats at exchanges and trade thousands in a day. So you have to really get specific in your question.
As far as daily Goal, that is very risky question or concept to think, really comes down to back testing that. After having 3,000 to 10,000 sample size should give you excellent idea of what you are seeking, but here is the thing, everything you know this minute, each year you will add to the questions based on your stats, you develop stats based on stats, by the minute, five minutes, entire day of minutes, pre-market, after market, the beat goes on as Sonny and Cher sang it. Best advise I can give, always test as it you were doing a one lot, if you can't make money on a one lot, more of them will mess up you up.
I look to make 6-7 points in ES in 60-75 minutes starting with pre-open, and I have to make 4pts then 6pts by so many minutes or I can't trade any more till full hour of regular day session, when I reach Goal, my platform cuts my volume 80%. I will do up to 40 trades in an hour as I am a Scalper going for smaller profits. Each different market I trade has same but different targets, time stops, signals and volume.
Now I know of couple other traders who do 1-3 trades during entire day session and they go for huge profits of 10-25pts in ES.
Comes down to you and spending huge amounts of time of finding ways to get there.
I agree with
wrbtrader , have to make this a business first.
Good luck.
