Charting System for US and UK

[mapidea]

I want to know which is the best system for analyzing charts for US and UK market. Though I trade indian markets, I want to have analysis for global cues.

I found http://www.freestockcharts.com/?gclid=CPXwzczW2KsCFQUb6wodCnlgPg

Is their any system available which doesn't cost much. Is location a constraint for opening the account. I am living in India.

Thanks.
