Пример сценария применения: использованиеMetaограничить объем активов, которыми управляет стратегия.

Сценарий применения: необходимо сделать капитальные лимиты для разных стратегических арендаторов.Metaзначение, установленное при генерации регистрационного кода, не может превышать 190 символов, аGetMeta()Если нет метаданных (Meta) устанавливается при генерировании кода регистрации стратегии,GetMeta()Функция возвращает null. Она не работает в системе обратного тестирования.
