Position size is the amount of money or number of shares committed to a single trade relative to your total bankroll.
Understanding position size helps you read prices and manage risk on any prediction market platform.
Example
Buying $20 worth of shares out of a $400 bankroll is a 5% position size.
Why it matters
Knowing how position size works lets you compare markets and avoid costly mistakes when trading.
Practical tip
Before trading, check how position size shows up on the specific platform you use, since interfaces and terminology can vary slightly between exchanges. Reviewing a few live markets is a quick way to see position size in action before risking real funds.
