I've been playing round with an automatic TA system called Autochartist of late. Am more into fundamentals myself but it's got the ability to at least help show the emerging support and resistance levels but it seems to look only at the very short term (unless I'm doing something wrong...)
If you look at http://www.cmcmarkets.co.uk/spread-betting/our-platform-markets there's no mention of it.
A mate said something to me earlier and I thought he'd lost the plot - probably need to download the demo...
