DECK

There is no other area of systematic trading that is so densely populated with mistakes and wishful thinking than backtesting.  In this workshop, we’re going to review and consider the most frequent — and the most dangerous among them.

CLASSES

We’re delighted with the strong demand for our upcoming educational program in systematic trading due start in June. Be sure to send in your application for consideration no later than May 29 in order to start in June and get yourself to the next level in systematic trading by the new back-to-work season.

Without any doubt, the biggest fallacy in back testing is being deluded in ignoring the feedback loop of changing in-sample parameters to accomplish good out-of-sample results. That is tantamount to transforming out of sample data to in-sample. There are guys here connected to me who will smile when they read this. Been there and done that 1000s of times. The best out of sample test is controlled by an independent person who takes control of your model and tests it in epochs you haven't explored. Or live testing.
