There is no "over and over" in the markets. A few times showcase and they catch up with you. better say find a small intraday edge constantly. But edge over whom? Professionals? market makers? value investors? or large well-informed insiders? You gotta tell me who is going to pay you for finding that edge. Who is going to lose money to you whose edge is inferior to yours. I maintain it can only be small time traders like you on the other side only.
