Rules-based investing
Systematic investing replaces judgment calls with written rules. These pages explain how rule-based strategies are built, the signals they use, and the traps in searching for rules that only look good in hindsight.
Systematic investing
What systematic, rules-based investing is, how it removes emotion from decisions, its advantages and pitfalls, and how to build a simple rule-based strategy.
If-then signals
How if-then signal rules work in rules-based strategies, the common condition types, how rules nest into decision trees, and how to keep them robust.
Frontrunner strategies
How the Frontrunner family of rules-based strategies buys short-term RSI dips in leveraged funds, why the idea spread, and the risks of these very active systems.
Signal mining and data snooping
What signal mining is, how testing millions of rules produces convincing but false results, and how to tell a real fundamental signal from data-mining luck.
