Moscow Exchange (MOEX) reported that at approximately 14:30 MSK on 16 January 2017, the Exchange’s IT team observed inaccurate operation of software used to produce order tables for one of the repo trading modes.
The malfunction could potentially result in errors in accepting orders from trading participants in other trading modes of the Equity & Bond Market.
The Exchange decided to suspend trading on the market at 14:34 MSK to adjust order table parameters and avoid potential negative impacts on the system’s clearing functions.
The trading system became available for order withdrawal starting from 15:05 MSK. Trading was resumed at 15:20 MSK. The trading and clearing system was unavailble for a total of 31 minutes.
Moscow Exchange’s other markets (FX, Derivatives and Commodities) operated as normal.
