How to read these figures

Trades counts every recorded trade in the portfolio’s history. The won-of-closed figure counts only closed fills that carry a recorded realized result in the published feed, so it covers the recent feed, not the full archive. S&P 500 and Nasdaq-100 figures are computed here from their published price series: biggest drop, positive days, Sharpe (30 days of daily returns, annualised, with no cash return deducted) and market sensitivity. Model figures are the publisher’s own.

Each portfolio is measured from its own start date, so this order is not a same-dates comparison.
