Не забываем предварительно подготовить и сохранить тайминги отдельным прогоном в тестере. При изменении параметров влияющих на тики(время, моделирование, добавление/удаление инструментов) необходимо повторно создать файл таймингов.

Версия для оптимизациия, использует dll . Эффективное использование оперативной памяти. Копия данных стакана только одна для каждого сивола, независимо от количества агентов тестирования на машине. Значительно быстрее работает по причине отсутсвия необходимости подготовки данных. Не работает на Windows 7.

Библиотека, включаемый файл и тестовый советник прилагается.

Version for optimization, uses dll . Efficient use of RAM. There is only one copy of DOM data for each character, regardless of the number of testing agents on the machine. Works much faster due to the lack of the need for data preparation. Doesn't work on Windows 7.

The library, include file and test EA are attached.
