Talk to a programmer and have them code it. Agree to a profit split ahead of time. But the other posters are likely correct. Good Luck.
Do you own anything you can sell or borrow against? Sell everything you own, max out your credit cards, cash in your life insurance, borrow from friends and family. Get a Canadian address and open an account. No PDT rule. If you want it bad enough there is a way.
I'm the idiot, you are right. You're the genius with a winning edge which you cannot even begin to paper trade, let alone even attempt to execute live. A winning edge that someone just gave to you, out of generosity, because they are obviously making way too much money with it. It's such injustice that investors are not breaking down door to give their money to you. Poor baby!
