We demonstrate the capabilities of\nthis method by applying it to high-frequency order book data from the EUREX\nexchange. We show that it is able to uncover (or recover) various relationships\nbetween all the first level order book events associated with some asset when\nmapped to a 12-dimensional process. We then scale up the model so as to account\nfor events on two assets simultaneously and we discuss the joint high-frequency\ndynamics.","url_abs":"http://arxiv.org/abs/1706.03411v1","url_pdf":"http://arxiv.org/pdf/1706.03411v1.pdf","source":{"archive":"pwc-archive (Hugging Face), CC BY-SA 4.0","snapshot":"2025-07-28","licence_url":"https://creativecommons.org/licenses/by-sa/4.0/legalcode","row_kind":"abstracts"},"code_links":[{"paper_slug":"analysis-of-order-book-flows-using-a","repo_url":"https://github.com/achab/nphc","is_official":0,"mentioned_in_paper":0,"mentioned_in_github":1,"framework":"none","reach":{"status":"ok"}}],"tasks":[],"methods":[],"datasets_introduced":[],"methods_introduced":[],"results":[],"syntology":{"syntology_url":null,"atlas_url":null,"mcp":null,"developers":"https://syntology.ai/developers"},"arxiv_metadata":null,"syntology_extracted_results":null}
