What is inside

Ten strategies, every rule on the page

100,000 kronor in an OMXS30 index fund 28 years ago would have been 494,145 kronor in 2026. The same capital traded on the ten strategies in this book, without reinvesting the profits, would have been 3,072,110 kronor. Those are the book’s own backtested figures, and a backtest is not a promise.

Every strategy is written out as entry and exit rules, tested on the OMXS30 index and then on the individual shares in it. The last part of the book prints the ProRealTime code and the backtest report for all eleven.

Strategy 0 is the worked example that teaches the format. Each strategy gets its rules, its results on the OMXS30 index, and a table of the individual shares it beat buy and hold on.

Before you buy

Is this your book?

Yes, if

  • You trade or invest in Swedish shares and want rules built on Swedish data
  • You read Swedish. The book has not been published in any other language
  • You want rules you can read, test and argue with, not a signal service
  • You have never run a backtest and want to understand what the numbers in one mean

No, if

  • You do not read Swedish. The S&P 500 edition covers the same ground in English
  • You want a daily signal to copy. The rules are printed, the execution is yours
  • You want options, crypto or intraday scalping. This is end of day work on shares and the index
