Delete expiry on indicator

Is it possible to delete the expiry date of this indicator by programming it differently?

I don´t want any limitation of this indicator. I know that programmers use programs to make the code hard to change by putting thousands of words in there which make no sense to hide the actual code. But I don´t have the actual source code of it.

Can someone do this ? If the price isn´t suitable for you we can talk about it if you really think it´s possible.

Thanks for your answers and effort.
