I trade the ES and make more than 2 points a day average. In the ES i don't think you can trade 500 contracts at once. About your proposal to trade for others: i don't want to trade for others because as a daytrader the size you can trade is limited. I will give you an example: if you start with 3000$ and reinvest your 2 points average profit per day your theoretical profit at the end of the year would be about 21,154,001,752,101 $ if there would be no limit on the size you can trade. But you would have to trade billions of contracts a day, so not realistic. So these calculations don't make any sense at all. You have to limit your number of contracts to a size that is manageable and realistic. If we limit the maximum size to 100 contract per trade the results of the 3000$ investment would be 2,113,900$. If i invest my own money i get the full profit; if i would trade for others my profit would only be the fee (so only a small part of the profit), in other words i would lose money by trading for others. Your explanation would be correct if the size that can be traded would largely exceed my own financial strength. So a good daytrader will never trade for others but will use the limited size at his own profit for 100%.
