I just saw a link for Old and Respected systems. Old is obvious, but how is respect measured?
At the beginning of that page, just below the title, is a short description. At the end of that description, it says "(Criteria for list)". Hover your mouse pointer over those words and you will see the answer.
on their page "These are systems that have performed well and have been tracked on Trading System Dashboard for at least six months."
Of course, "well" is a debatable concept, depending on equity curve and system stats…
