Nastavit Stop Loss, pokud cena překročí limit (kromě jedné)

Nastaví Stop Loss na zadanou úroveň, pokud je otevírací cena příkazu nad (pro long pozici) nebo pod (pro short pozici) cenovým limitem.

Pokud máte otevřeno více pozic, zabrání nastavení stop lossu na ztrátové pozice. To by mohlo pozici okamžitě uzavřít

As we open several market orders, we may have to close all orders except one position   ("Magic Number Excluded")
