Constants

Canonical reference for MQL5 constant enums, bit flags, and property identifiers.

This is a Reference skill: the body is a routing table into references/. Read the relevant reference file for the enum family you need.

Purpose

Catalogs every MQL5 enum family, property identifier, and bitmask flag used in the MQL5 API — account info, terminal info, chart events and properties, file I/O flags, object types and properties, symbol info, runtime error codes, trade return codes, and account access patterns.
