Testing one-letter tickers on securities market

Dear Securities market clients, 
Starting from 29 June 2018 an instrument with one-letter ticker symbol ('T') will be available on the INET_GATEWAY test environment. Such instruments may appear in production as part of the ongoing project to admit foreign issued securities for trading at MOEX. 
We would like to recommend you to check compatibility of your front office and backoffice software with one-letter ticker symbols.
