Sure, I get you are trying to obtain the correct information by making mistakes and hoping that someone smart/experienced will give you the right information but it doesn't work that way now, it used to but today, not.
"But some traders do want to build an auditable track record based on their trading strategy to have the option of raising funds for trading other peoples money if these so choose down the line." - they use AKJ or IB Friends & Family for however many years it takes as already explained.
"And of course when it comes to jurisdiction U.S. reins supreme both in terms of fund domicile and exchange choice and depth." - no it does not, the investors will often come from the US but the fund domicile is something completely different that is currently in fluid change, the past will not be the future.
Just as well I know the entity that has already done using forward projections what you are wanting to do looking in the mirror, they don't come to me to do the implementation work for nothing, you are using past projections/information/knowledge in all of your statements.
The experienced conclusion is that you are targeting the 'wishful thinkers' on a downward trajectory with more money than sense without any trading or architecture supporting them, what could go wrong, we've had these types as well but we were smart enough not to progress it to investor funding.
They wanted access to a +3 Sharpe methodology short tracking 3-5yrs down to 3-5moths without their putting all the ducks in a row, and us telling them to come back after a few years of AKJ or IB Friends & Family before it progressed too far, you would not do this, as I said the need for a revenue stream in 2023 is palpable.
It's always funny to see people with experience responding with the same knowledge presented in a different way to those who don't spend 24hrs digesting the information, it amuses me
