About PropMason

What PropMason Is

PropMason is a data-driven prop firm comparison site. It tracks the rules that proprietary trading firms publish — profit splits, drawdown limits, payout terms — and presents them side by side so traders can compare firms on the numbers that matter to them.

How the Data Is Produced

Rule fields are collected automatically from materials each firm publishes, and re-checked periodically. When a value changes, the new reading must hold for at least two days before it appears on the rule changelog — a first sighting is an observation, not a confirmed change. The checks behind every score are documented on the methodology page.
