How do you know a strategy is worth your time before trading it?

Time is the scarcest trading resource. A new strategy costs weeks of testing before it earns anything — so the screening question matters: does this have a reason to work, or just a good backtest?

What's your screen?

• the questions you ask before testing
• the red flags that end consideration
• the strategy that passed the screen and earned it

The expectancy guide supplies the screening maths.
