These files were replaced by new file formats upon the Chi-X Europe migration onto BATS technology back on 30th April, 2012.

The above legacy URLs will be no longer reachable from Thursday 28th February, 2013. This means that Wednesday 27th February, 2013 will be the last day upon which the legacy URLs will be accessible.

Any participants still using the above legacy URLs must now migrate to the new URLs.

Please refer to BATS Chi-X Europe Reference Data Documents for the new URLs and Reference Data Specification.

Please contact the Trade Desk or your Account Manager if you have any questions.
