Editing Technical analysis (section)

==Combination with other market forecast methods==
[[John Murphy (technical analyst)|John Murphy]] states that the principal sources of information available to technicians are price, volume and [[open interest]].<ref name=Murphy/> Other data, such as indicators and [[sentiment analysis]], are considered secondary.

However, many technical analysts reach outside pure technical analysis, combining other market forecast methods with their technical work. One advocate for this approach is [[John Bollinger]], who coined the term ''rational analysis'' in the middle 1980s for the intersection of technical analysis and fundamental analysis.<ref>{{cite web|url=http://www.researchandmarkets.com/reports/450723/the_capital_growth_letter.htm|title=The Capital Growth Letter – Research and Markets|first=Research and Markets|last=ltd}}</ref> Another such approach, fusion analysis, overlays fundamental analysis with technical, in an attempt to improve portfolio manager performance.

Technical analysis is also often combined with [[Quantitative analyst|quantitative analysis]] and economics. For example, neural networks may be used to help identify intermarket relationships.<ref>{{Cite web |url=http://www.iijournals.com/JOT/default.asp?Page=2&ISS=22278&SID=644085 |title=Archived copy |access-date=31 August 2007 |archive-date=12 January 2009 |archive-url=https://web.archive.org/web/20090112164116/http://www.iijournals.com/JOT/default.asp?Page=2&ISS=22278&SID=644085 |url-status=dead }}</ref>

Investor and newsletter polls, and magazine cover sentiment indicators, are also used by technical analysts.<ref>{{cite web|url=http://www.sfomag.com/departmentprintdetail.asp?ID=1776333475|title=SFO|access-date=27 August 2007|archive-url=https://web.archive.org/web/20071006150127/http://www.sfomag.com/departmentprintdetail.asp?ID=1776333475|archive-date=6 October 2007|url-status=usurped}}</ref>
