(29)In terms of the services provided by trade repositories, Regulation (EU) No 648/2012 has established a competitive environment. Counterparties should therefore be able to choose the trade repository to which they wish to report and should be able to switch trade repositories if they so choose. To facilitate such switching and to ensure the continued availability of data without duplication, trade repositories should establish appropriate policies to ensure the orderly transfer of data reported to other trade repositories where requested by a counterparty that is subject to the reporting obligation.
