Indeed. Mathematically it all works out to be the same thing. When working with numbers like $30,000,000 account size however, there are other niggly bits, like the number of contracts to make it happen, along with contract limits, plus the psychology factor of it all.
I can only guess as to how one could turn 30Mil into 210Mil.
It takes years of overcoming what I call "mindf*ucked" dealing with numbers. My Business partner has "mindf*ucked" the worst but is great trader if I am sitting next to him, but once I leave he is like deer in headlights, but he knows my systems better than I do, thankfully he can program whereas I no longer have that ability, one too many procedures done. He and I are honestly thinking of in handful or less years starting a hedge fund with our own funds. We thinking of starting with 4k, 2k each and see how fast automation will run it up, then add a sizeable more to attract money. Plus it will take that long to automated many systems I have developed and changed due to risk management.
Trading size has to do with open of the markets, London has 90 minutes of good trading, then Chicago, Hong Kong all the same 90 minutes. So in these times you can run size without too much problems, then after you cut back and go from scalping to much longer profits which can also be done at start of day and run 23 hours in most markets, coffee as well. But scalping after 90 minutes, it is getting tougher each year as volume is shrinking and causing bars to be smaller in range.
There are many many ways to different markets, where truly the problem comes in is how to offset risk. Some of my styles of trading is balls to the wall in day trading, but when you come to equities, it is tougher as Stock market goes up, your size has to start coming down to be safe, and some firms will hedge using ES when it gets toppy.
I trade differently than most I suppose as when markets hit an area based on 9 years, I start going counter/hedged in futures and yet am still long stocks but as going higher-percentages gets tighter as far as targets and amount to keep hoping for longer term prospects is reduced. So my way has some parity to overall stock market but am strictly limited in futures to options available at decent prices, but can always go to SPX options for offset risk as well. One has to find alternative ways to cover risk better.
I have become much more conservative several years ago as back testing shows I can do better by thinking "risk" first and profits second, and bottom line has changed for better, but biggest improvement is drawdowns not as wild and equity swing much much smoother, so what has happened is my percentages of winning trades have stayed same, losing trades gone down and better than breakeven trades have increased double. So I am making more end of the year, cause I am losing less often, this in turn allows for more trading and on margin-first time in my life in stocks. Less staggering drawdowns.
I love playing the "game" as it is often times all I think about even after 39 years, I love to challenge myself and how to overcome situations. Longer you stay, you find it always been you against you that either makes you profitable or not.
