For some reason, the labels "H4 SMA" and "H1 SMA" are not being rendered on the y-axis where the H1 SMA has been calculated. 

 Instead, they are always rendered at the exact same place on every chart that I put this EA on.

How can I get the labels to render at the computed value of the SMA?

 ObjectCreate("H4_SMA",OBJ_LABEL,0,Time[1],H4_SMA);
   ObjectSetText("H4_SMA","H4 SMA",14,"Tahoma",Gold);

OBJ_LABEL is not positioned according to time and price, it is by pixels on the x-y axis

Use OBJ_TEXT if you want to use time and price

From ObjectCreate() help:

 

Note

Objects of the OBJ_LABEL type ignore the coordinates. Use the ObjectSet() function to set up the OBJPROP_XDISTANCE and OBJPROP_YDISTANCE properties.
