Due to the possible severity of hurricane Dorian, it is possible that our clients may experience interruptions of service. Although we have co-located our critical systems in a secure place that has guaranteed power uptime and redundant communication lines, the unpredictability of the storm’s path and level of destruction may cause disruptions. The staff of CSI will give its best efforts to conduct business, but must also consider the safety of each team member.

U.S. and Canadian Markets will be closed Monday 9-2-2019 for the Labor Day holiday.

Please be advised that effective January 14, 2019, CSI will amend quotations of certain NCDEX products in order to provide more accurate price and volume precision.

One or more of the latest Microsoft Windows Security Updates has interfered with the
functioning of the Microsoft Excel ODBC Driver that is used by UA to manage Excel export
files. We have confirmed this is an issue with Microsoft, and that they’ve been
notified. The only way for us to handle this for now is to uninstall their security update.
This can be done from your Control Panel’s Program and Features interface.
Go there and click View Installed updates. Locate one of the following updates,
select it and click Uninstall. Your system will run through the uninstall process and
prompt you to reboot. After this is done, your Excel export files can then again
be managed properly.
