I've always operated on the premise that even if systems had a bad run, they would always come back. Once they did, it would vindicate the initial design. I'm maintaining these older systems to provide a record for myself and anyone who may be interested. Systems listed on this paged are either no longer supported, no longer traded, not recommended for trading, or under development. Data will continue to flow intermittently to these pages so you should still be able to click on the links below and get charts which reflect current up to date performance data. If something is not up to date and you want it updated, just send an email.
