3M TAS (price code “TC” Trade at Close)

Bloomberg does not currently display TAS orders/trades with differential prices from LMEselect TAS instrument orderbooks. TAS trades with absolute prices are shown on the parent contract page only after price is substituted and not at time of trade. To distinguish TAS trades with parent contract trades - a 'TAS' indicator is displayed next to TAS trade.
