A contrarian writes

I have now looked up the word 'contrarian', and it seems that I have used it correctly, although as I suspected it could well be argued that the notion of 'wilful' is an intricate part of being contrarian. But what surprises me as that the online Oxford English Dictionary returns a 'not found' result when you ask it to define 'contrarian', as does the online Collins dictionary. However, if you google 'contrarian' you come up with may references. The key to this slight mystery is that it seems the word is more commonly used in investment circles and in an economic context (which, I must admit, was news to me) as in a guy taking the opposite - investment - tack to accepted wisdom. Fascinating? Perhaps not. I think whether or not you find this entry interesting will depend on how bored you are.
