Its better to have both when you do have the chance yet we know that fundamentals doesnt come out very often which means if you do rely on news and other aspect then you would really be on stagnant knowing that
this market doesnt generate out time to time news unlike on traditional markets like forex and stocks.

Fundamentals and technicals can be correlated but we know that no matter how good your analysis is, it is still bound to fail yet this market is always been unpredictable.It can neither break nor follow those kind of analysis.

When it comes to importance then it all vary on which one do give out profit into you but majority is been using technicals in regards into their trades.
