your function ATR returns a double, but at the very end of this function nothing is returend. Put there a return(-1.) as a signal the function failed? - As there is practically nothing that does not exists for MT4 have you searched (top-right and google)?

Hi,
I have a couple issues/questions with my indicator, also feel free to add any tips. I'm not a programmer by profession and new to mql4.
- the main issue is that none of these are showing at all, I put these in the function OnCalculate as they have to move dynamically:
ObjectCreate("top 0.7 ATR", OBJ_HLINE, 0, Time[0], ATR_levels("xATR","xATRUP"),0 ,0);
ObjectCreate("bottom 0.7 ATR", OBJ_HLINE, 0, Time[0], 0, ATR_levels("xATR","xATRDOWN"), 0);
ObjectCreate("top 0.8 ATR", OBJ_HLINE, 0, Time[0], 0, ATR_levels("yATR","yATRUP"), 0);
ObjectCreate("bottom 0.8 ATR", OBJ_HLINE, 0, Time[0], 0, ATR_levels("yATR","yATRDOWN"), 0);
what they are meant to do is to draw lines of lowest point of the day + 0.7 ATR, highest point of the day - 0.7 ATR and the same for 0.8 ATR.
-the function, ATR_levels I created, I'd say works correctly but I don't understand why I get this error: not all control paths return a value Morning Glory.mq4 133 4
I removed the property strict which apparently sometimes causes this error.
I hope this makes sense and I thank you for taking the time to have a look.
