# Reference

> DerivaDEX reference documentation for trading specifications, margin and pricing inputs, funding and settlement rules, rate limits, safeguards, errors, and event fields.

Reference is for exact answers. Use these pages when you need the rule, limit, formula, or field definition without the longer walkthrough.
