Reactor Library 📚

For a weekend read, Thinking, Fast and Slow by Daniel Kahneman is still one of the more useful books for anyone who makes decisions under uncertainty.

One idea from the book is particularly relevant to trading: recent results can have a disproportionate influence on how we judge what happens next.

A strategy makes money for a few trades, and suddenly its logic feels obvious.

The same strategy loses a few trades later, and the rules that seemed convincing start looking broken.

Neither conclusion necessarily follows from such a small sample.

This is one reason testing a strategy over a larger set of conditions can be more useful than judging it from the last few trades.

The Trading Sandbox gives you room to experiment without attaching real capital to every conclusion.

👉 Put the idea to the test
