I don't pretend to be a technical analyst, in fact I lean towards fundamental analysis. However, I am learning that fundamental analysis (earnings, revenue, etc.) doesn't work particularly well for small companies that either don't have any revenue to speak of or who fail to report it if they do.
However, I use a charting service called Barchart (you can google Barchart easily). Membership is free (you can also buy a premium membership that I do not have). Regardless, site loads of tech data including support and resistance. I have only just scratched the surface.
I am sure this data is also available on many other service sites as well.
