(12)For certain trading models, increased accuracy to which business clocks are to be synchronised might not be relevant or feasible. Voice trading systems or request for quote trading systems, where the response requires human intervention or does not allow algorithmic trading, or systems which are used for concluding negotiated transactions, should thus be subject to different accuracy standards. Trading venues operating those trading systems are not typically susceptible to the high volume of events that can happen within the same second. Since it is less likely that there are multiple events occurring at the same time, it is not necessary to impose a finer granularity to time stamping of those events. In addition, trades on those trading venues may be agreed using manual methods which can take time. On those trading venues there is also an inherent delay between the moment the trade is executed and the moment the trade is recorded in the trading system. Imposing more stringent accuracy requirements would therefore not necessarily lead to more meaningful and accurate record keeping by the operator of the trading venue, its members, participants or users.
