Hello, I'm RegentsPark. I wanted to let you know that one or more of your recent contributions to Pairs trading have been undone because they appeared to be promotional. Advertising and using Wikipedia as a "soapbox" are against Wikipedia policy and not permitted; Wikipedia articles should be written objectively, using independent sources, and from a neutral perspective. Take a look at the welcome page to learn more about Wikipedia. Thank you. regentspark (comment) 12:12, 12 September 2017 (UTC)
