It is interesting that a one-liner question generated 37 pages of comments. And the OP had never followed up since the starter.
Seriously man just give up trying to explain it to him. He doesn't know how to trade, period. Just another one on ignore. Good trading.
also, while 300 - 400 per day is reasonable, it will not ever happen if you dont ask the more important question of how much is reasonable to risk per day? per trade? per week? per month? and what you will do when you hit your loss limits for each period. Those are much more important questions to focus on than how much money you want to make. I promise you you won't make a dime unless you focus on the opposite of what seems natural. focus on your losses not your gains.
While papertraders often have no problem acheiving this goal, as risk has no meaning when no money is on the table. $400 a day is $400*270 trading days a year, or about $110K a year. Throw in trading costs, and maybe you need to pull $130-150K, or up to 300% annual return. And on the longterm? Slash the chance of doing this by perhaps a factor of 50. Take a look at timertrac, robbins world cup, collective2, futurestruth and the other dusiters and see how very very very few do this when PAPER trading without worry of risk. And your statement vanishes like smoke in a hurricane. Throw in risk of ruin, errors, taxes and other things, and it is beyond ludicrous for people to "expect" this kind of return.
In Theory and it is simple math If your system wins 40% of the time and your wins are 3 times larger than your loses and you risk 1% of your capital per trade 1 trade a day should give you an average win of $300/day In Theory
You do realize that this is over 200% annualized return right? If you figure out how to get a 200% return on a regular basis I'll be willing to pay you $500 a day just for you to teach me your ways.
Do you even trade? Do you know any traders? I don't know any traders who talk about "X% annualized return" in reference to their performance. Oh and if it were that easy to take someone's money and "teach" that person how to trade...lol.
