I never said that? Scaling can be an issue for certain types of trades. By the time scaling would even begin to be an issue for me personally, I will have already had the amount of resources I personally would need or want for my life. So I don't understand why I should overly concern myself with someone making billions, when they have the resources, technology, connections and access to things currently far beyond my reach. What sense would that make at the current moment? I should not use the TA that is working very well for me, because someone making billions says it doesn't work? Or they can't employ some of the strategies I use due to scalability and potential sizing issues?
I am going off of results I've seen from others, as well as my personal experience trading and don't really have a dog in the fight if others agree or disagree. With that said your random equivalent to a surgeon comparison fails to make sense to me. What is your suggestion, I stop doing what is working because people managing billions of dollars don't or can't apply the same strategies I do?
If you're talking about hundreds of thousands to in the lower end of millions per year, than if I had the resources you do, fairly confident I would do just as well as you if not better.
If we're talking about making hundreds of millions to billions of dollars, than in that case I can fully admit am not currently in a position to speak on that and would have to drastically change what I do and how I do it, to pull in that type of income.
