Use the Settings menu to control the update of margin parameters, product specifications and other parameters like vola offsets and maturity based multipliers. All parameters and product specifications may be adjusted manually, or updated from the website (Market Data > Clearing Data > Risk Parameters; Eurex Clearing uploads daily updates to the margin parameters file; the product specifications file is updated every three to four months.) Depending on the level of restriction within your company's firewall settings, importing data from the website may not be possible; the same may occur when using a proxy server requiring a password. In this case, you can adjust the path for the update files to a local drive, where you have stored the update files manually (or to where you have copied them from the Eurex website using an automated cron job). Please contact your system administrator in such cases.
