Du musst die Objekte unterschiedlich benennen.
PHP-Code:
double value1 = 1.2930;
ObjectDelete("HorizontaleLinie1");
ObjectCreate("HorizontaleLinie1", OBJ_HLINE,0,Time[0],value1);
ObjectSet("HorizontaleLinie1", OBJPROP_COLOR, Yellow);
double value2 = 1.2930;
ObjectDelete("HorizontaleLinie2");
ObjectCreate("HorizontaleLinie2", OBJ_HLINE,0,Time[0],value2);
ObjectSet("HorizontaleLinie2", OBJPROP_COLOR, Blue);
s.l.
