Customizable Pivot Point Indicator

Hi, 

I love the fact that now I can get an indicator automatically installed onto my cTrader for Mac. Now, I looked at both paid pivot point indicators for sale, but neither of them really give details on what actually get. I would like an indicator that I can set to the 1 hour, 4 hour, or daily calculations, but neither paid indicator describes if they allow this. Is there a way for you to allow people to contact the developers of these indicators to ask a question?
