For a couple years, I used to hang out on a site that let me write trading scripts (formulas) and test them. It let me try other scripts that previous traders had developed for us. It had quality message boards, post editing at any time, HTML on charts and pictures, investor/trader contests, and portfolio tracking.
The problem was, I was about the only active trader that hung out there. And now, of course, I have misplaced the link.
Does anyone have any idea of what the site might have been called?
