Bid Tick (Column)

The bid tick indicator is an arrow that indicates the change in the bid price of a symbol. Nasdaq requires the display of the bid tick indicator for all Nasdaq National Market securities. In the Time & Sales window, the bid tick indicator is shown as an up or down arrow in the Quote Bar.

If the bid tick is up, the indicator appears as a green, up arrow, or a plus sign (+). When the bid tick is down, indicator appears as a red, down arrow, or a minus sign (-). The bid tick indicator is not an indication of an up or downtick of the symbol's last price, but rather the bid price of the symbol.
