How does confidentiality work in Arena?

Confidentiality is the reason Arena exists. Sensitive figures — commissions, margins, internal notes — are hidden by default. In each operation you answer simple yes/no questions about who should know what, and those answers become access rules enforced on every screen and every secure link. A broker can see both sides of a back-to-back deal while neither the buyer nor the seller learns the other's price. You stay in control and can adjust the rules until the operation closes.
