I'm using the Market Analyzer Professional (MAPro) 2000 Version (which is the Old-but-Original that evolved from Year 2000 Version), which I started using since 2003-2004 I think. You can get it from the provider MDSNews.com now with their new Platinum or Gold Versions which I think not as good the MAPro 2000 version.
Anyway, they come with 1-minute, 5, 10, 15 etc. etc. depending on how you want to tune your Intraday Charting.
BTW, I'm not flagging this software, but since you ask me what I use, then there you are.
I'm sure there are a dozen or more platforms in the market that's probably better than what I have, but it's like my car, I really would like to be comfortable in driving it if I'm going to make use of it for myself. That's how I see these sort of charting tools and softwares.
They are not free though, but it's worth the price for the information and guidance you can get to make more dough, or minimise your losses.
Hope this helps.
Cheers,
