Why Size

Anyone can trade. Few can trade well.

Trading is hard. Most people burn through their savings trying to learn and no one tells them what went wrong. They just have less money than they started with.
On Size you can win a funded trading account without ever trading your own money, and you find out what went wrong every run, win or lose.

How we measure skill

Your Trial score comes from how you played

You can trade well and still lose money over 15 minutes. That doesn't cost you the Trial on Size, because we can see what you actually did. We measure things like:

  • Your sizing
  • Your entries and exits
  • What you do when a trade moves against you
  • Whether any of that changes after you take a loss

Your PnL is one input among many so you can still win a Life without profit.
