indicator error - initialization

[rodrigosm]

Hi everybody,

I was trying to realize where is the problem on this indicator formula. When I insert it on the graphic, it's plot two horizontal lines, so, I have to open the code and click again on "Compile" button. Another problem is: When a new bar appears, the lines change dramatically for a second.

Here is the code:

Anyone knows where is the problem?
