Not sure about scaling, usually easier said than done unless you get an edge in say ES during RTH.Are you saying you would rather sell/pawn your ideas/strategies than trade them yourself? I don't know what your vehicle is but a strategy worth real money should scale far beyond what any other vehicles can offer (except illegal ones of course). The only way I would buy any strategy (track record or not) is in some kind of installment plan based on real money performance. I would want the strategy pay itself off.
My other vehicle is my wholesale business, completely unrelated to trading and also pretty scalable and growing, so far see no limit on it to swallow any money lol.
