Sectors analysis

Hi Guys!
I am looking for a free software or Web page that allows me to do charting analysis of industrial sectors. I see some people in YouTube doing technical analysis of sectors in the same way they do with individual stocks. I have TD Ameritrade software (Strategy Desk) but there is not way to do sectors analysis. I found this Website: Welcome to Barchart.com that offers a lot of information but is not that good with charts and does not have the possibilities to include serious technical analysis in sectors. Please! I would appreciate any input or advice about this topic. Thanks in advance.

Thank you in advance.

This is amazing! No one of the experienced participating members could help me with my question.
