Beginner decision framework

When studying Jim Simons, convert the style into a clear process before using real capital. A process keeps decisions from being driven only by news or emotion.

What is the main edge or thesis?

What would prove me wrong?

If wrong, how much can I lose and can I recover?

Does this decision fit my time horizon and temperament?
