When heavy scalping the ES I am learning that about half the time many trades start out with 1 contract and end up with 2, 3 or 4 or contracts in the end. Why do you think we have a ladder (DOM)? When the trade set is over and you get one tick over/under the average you end up with 1, 2 or 3 losing trades and 1 winning trade. The length of this trade depends upon if you trade the day session (under 1 minute) or night session (up to 10 minutes). In the day session you may have to wait for each trade to present itself each 5 minutes on average, night session maybe 15 minutes average.
You have a 6k account with a company like Tradovate that will give you a DOM with all the bells and whistles and free charting for $2.58 R/T "all in" plus $2,400.00 year membership prepaid. The commission is important then you lease a spot from the exchange eventually.
Heavy scalpers can make a lot of money. An insane amount of money. You can calculate it from this post. At $12.50 profit (1 ES tick) for one R/T - commish of $2.58 = $9.92/RT per 6 minutes. If you work days only for 4 hours for 220 days (one year) at 10 trades per hour = $87,296.00 - $2,388.00 = $84,908.00 per year. Nights give about 3 trades/hour.
So the terrible winrate gives you a $84,908.00 for a $6,000.00 investment. 880 hours of labor at$30.00 per hour = $26,400.00. So that leaves you $58,508.00 to reinvest in your trading account to increase your contracts. The sky then becomes the limit.

P. S. cut everything in half if you are a negative person. The reinvestment in your trading account along the way will solve all of your negativity. Hey all that for 30 bucks an hour
P.S.S. One small detail I left out...you gotta know how to scalp for one tick and never lose a trade set

So far I have simulated 1,500 trades working day and night for 10 days practicing without losing one trade set. I have 6 months to a year to go practice practice...practice and then more practice. I beleive it will be worth it in the end don't you?
