In the original version of this article, there was a typographical error in the spelling of the author Shun-ichi Amano which was incorrectly given as Sun-ichi Amano.

In addition, Reference 11 was incorrectly given as: ‘Sun, X., Shen, H., Cheng, X. & Wang, Z. Degree-strength correlation reveal anomalous trading behaviour. PLoS One 7, e45598 (2012).’

These errors have now been corrected in the HTML and PDF versions of the Article.
