There's a single number that decides whether your next trade is a genuine 2:1 setup or a coin flip, and it has nothing to do with the stock, the coin, or the setup you picked.

It isn't your stop loss.

It isn't your position size.

It isn't the indicator still loading on your screen.

It isn't even the trade itself.

It's something that happens in the handful of seconds between when you first saw the setup and when you actually clicked buy.

Traders have a name for it. They call it the chase.

There's a hard line buried inside it, one exact percentage point where a textbook 2:1 setup turns into a coin flip, before a single candle even closes.

A fixed stop and a fixed target stay put no matter where the entry lands.

That means every second of hesitation, or every second of pure FOMO, is doing math against you, whether you're watching it happen or not.

A separate, much bigger version of the same pattern shows up in a well-known annual study of ten years of fund investor behavior, the kind of study that tracks actual dollars, not opinions.

It found investors giving back a measured share of their own funds' returns, for a reason that had nothing to do with picking the wrong fund.

Two simulations built for this report, one running 20,000 accounts and one running an exact probability calculation, both landed on the same conclusion from two completely different directions.

The exact line, the math behind it, the study, and what it does to an account over 100 ordinary trades are all laid out below, with the page number where each piece lives.
