Used on the consolidated tape to mean that volume data for trades of 10,000 shares and fewer will be omitted until further notice. The deletion of volume, the next step following the deletion of certain digits of price information, is intended to speed the reporting of trades during periods of very heavy volume. With volume and all data but the digits and fractions deleted, a trade that ordinarily appears as XOM 5s41.3 will be reported as XOM 1.3.
