Modify existing MT4 indicator

I have an existing MT4 indicator (source code will be supplied) that I would like two small changes.

Change 1: The indicator should only draw lines from their creation date forwards (currently lines extend backwards before their creation date, as well as forwards);

Change 2: Lines relating to the current year I want in a different colour (or type) to indicate they are not fixed and subject to change.

I don't want the fastest, I want quality tested code.

I have more jobs after this one, looking for a long term strategic partnership.

Thanks!
