Okay. I am not capable of fully discussing what "those who make it big" do or don't do, as I only know two personally who have. Both are discretionary traders; one using price, volume, and time to choose entries and exits; the other using price and several mathematical derivatives of price to time entries and exits. I'd wager the second could do just as well without the derivatives. Neither hold trades beyond intraday. Neither talk in terms of "models".
So back to my questions, which, forgive me if I don't see it, don't appear to be answered in your response: what do your "models" consist of? Are "models" a means of determining an entry location and an exit location, be it profitable or at a loss? And, if so, are your "models" a product of a combination of price, volume, and/or time? Or are they a product of derivations of those three? Or something all together completely different (i.e. lunar phase, Twitter sentiment, etc.)?
Thanks for your time -
Like all models they base decisions based on data, theories, assumptions, analyses, hypotheses/etc within methodological frameworks.. I would not be able to discuss the specifics, but please feel free to PM me if you have any question/comment that I could answer or discuss. Thanks for your polite and thoughtful post.
