Potrzebuje do swojego systemu wskaznik Tema w takiej postaci TEMA(close,period)
Nie wiem co zle robie ale nie dzialała tzn zmienna Var1 ktora powinna miec wartosc funkcji Tema(close,4) to jest pusta, Zle cos przekazuje ?
Robie to tak:

Ogolnie to problem jedyny jaki jest to przy wywaołaniu tutaj:
Var1 = Tema(Apply_To_Price,4);
w Var1 nie przypisuje zadnych wartosci ...
Pytanie jak wyciagnac te wartosci z tej funkcji ?
