I guess the question is “what is successful” and “trading for a living”? Like how much money are they making a year and as a % pnl wise? And how does that compare to SPX performance for that period?
Cohen at SAC was trading something like 20K ES trips a day as a hobby. No, you're never going to have capacity issues in index futs.
You are the absolute king of assuming - where did I say candlesticks? Where? You like everyone else in this world (me too) that hasn't worked behind the scenes in RenTech have no friggen' clue what they do. Done replying to you. If need be by hitting the button.
It's difficult talking to you because you don't fully read what people say and/or comprehend it. But I will practice patience and explain to you again. Yeah it's considered live-sim account, but it's via the online prop firms, which I've been paid out before and we currently have the accounts up enough to take withdrawals out of. So it's real money consequences. Why do I care if it's sim or live? They pay out, because most people fail to pass the test and can't handle the live trailing draw down once they move to funded. You would think out of all the expert traders we have here, someone would just pass one and get a pay out to show how good they are, as oppose to having silly arguments.
I already said by the time I ever reach capacity issues I would have the resources I need / want for my life. You do realize my comment was related to the gentleman talking about managing and making hundreds of millions and billions of dollars correct? NQ is not as generous at ES. But if you're saying I could apply enough capital to make millions and millions on a smaller time frame setup and not effect it, despite there being less than 100 and even less than 60 contracts on some of the bars I trade, than I'll have to take your word for it.
I don't know their exact net worth or how much capital was in the account. The guy who traded for 25+ years, I've seen him have multiple 30-50k days and some 100k+ days trading ES. The other guy made a lot less, like 4-8k days on average. Suffice to say successful enough in my book. Hopefully you can appreciate that it's irrelevant to me if you consider that successful or not, we are different people likely with different goals.
Nobody can hit the mkt with 10K offered mkt and think they won't sweep the book. No, there is not unlimited liquidity at a price. That doesn't define capacity. I don't understand how this relates to applying stochastics or whatever to the markets. Analytical method has nothing to do with ability to fill size at a price. This thread has gone off the rails, but you've answered your own question--you'll lose interest before you reach whatever capacity issues are there.
