Помогите исправить ошибку в коде

Вообщем, не могу соединить два условия вместе:

Вот как я это понимаю:

#property  indicator_separate_window
#property  indicator_buffers 5
#property  indicator_color1  Black
#property  indicator_color2  Green
#property  indicator_color3  Green
#property  indicator_color4  Red
#property  indicator_color5  Red
//---- indicator buffers

double     ExtUpBuffer[];
double     ExtUp2Buffer[];
double     ExtDnBuffer[];
double     ExtDn2Buffer[];

double     ExtMacdBuffer[];
double     ExtSignalBuffer[];

Однако, метатрейдер меня не слушает и индикатор не запускается. Люди добрые помогите, пожалуйста!
