Новый комментарий

В интернете нашел ссылку на торговлю золотом:

***

Сделал простенькую программу:

Кому не сложно, подправьте пожалуйста , для торговли на демо.

Торговый план :

-четверг на закрытии рынка - ордер BUY,

- пятница на закрытии  рынка закрыть BUY, открыть ордер SELL,

- понедельник на закрытии рынка - закрыть ордер SELL.
