RETRACTED: Pricing currency options based on fuzzy techniques

This article has been retracted at the request of the Editor-in-Chief. Please see Elsevier Policy on Article Withdrawal (http://www.elsevier.com/locate/withdrawalpolicy).Reason: The author has plagiarized part of a paper that had already appeared in Comput. Oper. Res., 31 (2004) 1069–1081, doi:10.1016/S0305-0548(03)00065-0. One of the conditions of submission of a paper for publication is that authors declare explicitly that their work is original and has not appeared in a publication elsewhere. As such, this article represents a severe abuse of the scientific publishing system. The scientific community takes a very strong view on this matter and we apologize to readers of the journal that this was not detected during the submission process.
