Can you give me a sample of how to call this function Watermark (); so I may learn?

Can I just put the following, and will it work??

ObjectCreate("Forex-Grail", OBJ_LABEL, 0, 0, 0);
ObjectSetText("Forex-Grail", "Forex-Grail", 11, "Lucida Handwriting", RoyalBlue);
ObjectSet("Forex-Grail", OBJPROP_CORNER, 3);
ObjectSet("Forex-Grail", OBJPROP_XDISTANCE, 5);
ObjectSet("Forex-Grail", OBJPROP_YDISTANCE, 10);
return(0);

I just tried the above, it compiled with no errors, but nothing shows on the graph! Frustrating.

I have a good working ea that is still in the test stages, and do not want to reveal the code of the ea.
