SMALL PRICE · BIG VALUE · SHORT EDITION

Every strategy has bad runs, and some really do stop working. From the inside the two can look the same. This guide gives you a written review process: decide what is being tested, keep records you can trust, see how much a streak or a small sample can really tell you, and decide on evidence whether to keep, change, pause or retire a method.

What's inside

  • Defining the method, the version and net R before you judge it
  • Reviewing process and outcomes on two separate tracks
  • What losing streaks, small samples and lucky results can and cannot show, with exact worked figures
  • Keeping the testing history visible, changing with a record, and pausing or retiring without having to prove failure

What you get

  • An 18-page PDF with clickable contents, readable on phone, tablet or desktop
  • Keep, Change or Retire Worksheets (six fillable pages)
  • Plain-English explanations, worked arithmetic you can check, and sources listed at the back

Included free with Probability, Not Prediction. The £2.99 price applies only when you buy this short edition on its own.
