Mathematicians hired to monitor transactions 

I removed the following part of the article:

 Business.dk reported that the bank has a team of mathematicians employed to surveil the clients' trading patterns.

Saxo Bank is not doing anything untraditional in employing mathematicians, since indeed most larger financial institutions employ a number of mathematicians, economists and even physicists. To a lay reader this may sound incriminating or disturbing, but the main task of these employees is in fact to improve the trading systems performance in relation to speed and pricing, and safety in relation to sniping and other unauthorized activity. 

Furthermore, the secret source in the business.dk article referenced claims that Saxo employs these mathematicians to monitor individual trading patterns (in order to take unfair advantage of customers). However, and this is not stated in the business.dk article: Saxo shows the same two-sided price, for the same amount, at the same time, to any and all clients trading. This means that no single clients trading pattern is of interest. 

Therefore the accusation in the business.dk article is not only wrong, but also shows the lack of insight from the secret source and the journalist who wrote it. The fact that an article was brought in an online newspaper does not excuse wrong information. In relation to this particular statement regarding the role of the employed mathematicians, therefore, the article is in my opinion an unreliable source, in accordance with the Wikipedia principles of WP:IRS

Either this information regarding the widespread use of mathematicians among larger financial institutions, and regarding Saxo showing the two-sided price etc. should be included, (which I originally did until it was removed) to clarify to the lay reader that this is not uncommon or suspicious, and correct the mistaken information in the business.dk article, or the information about employing mathematicians should be left out completely, to preserve the neutrality of the article.
