# constants

`aiomql.core.constants` — MetaTrader 5 constants as Pythonic `IntEnum` types.

## Overview

Wraps every MT5 constant group into a typed Python enum. Each enum inherits from `Repr`
(which provides MT5-style `__str__`) and `IntEnum`, giving both type safety and integer
interoperability with the MT5 API.

## Classes
