You opened a thread a few weeks ago, I guess its related unless you're modelling the weather. If you're trading with your own money for your own benefit, a prop shop essentially, then you can I'm sure you can be as flexible as you like and no one will care.
If it's a silly/weak workaround to essentially offering investment advice under some vague get-out-clause that your clients (or friends) are buying into a mathematical model, or recurring modelling advice, and even executing themselves then you will be truly, and rightfully, screwed the moment you learn that your clients/friends can also pretend, and they were never allegedly aware of the risks.
You're attempting to enter the most regulated industry outside of drugs, the back doors don't exist.
