"I built RiskScale after one too many trades where I found out about the offering after I was already in the name. Every calculation here is the same math I use on my own size before I click buy."

The problem

Most blown accounts aren't
bad trades. They're bad sizes.

You can be right on direction and still get wrecked because the position was too big for the stop you actually needed.

—
Guessing share count under pressureDoing ATR math in your head while a low-float name is already moving isn't a plan.
—
Getting caught in a dilutive offeringLow-float squeezes are exactly where companies file shelfs and ATMs — and exactly where traders don't check.
—
A stop that doesn't match the stock's volatilityA fixed percent stop on a high-ATR name means you're sized way too big for what you'll actually risk.
