NYSE Advance/Decline from IB
The NYSE Advancing and Declining Issues are available in the IB version of Investor/RT using the ticker symbol AD-NYSE. The AD-NYSE instrument must be setup as an âIndexâ with Override Exchange code NYSE. This is an unusual IB symbol. The advancing issue count is transmitted via the bid and the declining issue count as the ask price. The number of unchanged NYSE issues is reported in the âBid Sizeâ. No âLast priceâ is transmitted for this symbol.
Changes were made to Investor/RT 8.5.2 for IB to allow the advances, the declines, or the difference or ratio of the two to be easily tracked using custom instruments. First, the bid (advances) of AD-NYSE is mapped by Investor/RT to the last so that a simple line chart of AD-NYSE will show you how the advancing issues changes over time. To see the declines, setup a custom instrument (Setup: Custom Instrument), a âsumâ of just one component AD-NSYE using the ask price for that one component.
To track the advances minus the declines or the advance/decline ratio, create a custom instrument with two components as a âdifferenceâ or a âratioâ. Both components will specify AD-NYSE with the bid price specified for the first component and the ask price specified for the second component.
The IB ticker symbol VOL-NYSE works similarly. The advancing volume is reported in the bid, the declining volume in the ask, and the unchanged volume in the bid size. Similar custom instruments can be setup easily to track the NYSE advance/decline volume spread or ratio.
Historical data for these custom instruments is not available. The custom instruments will update in real-time for charting or display in quotepages. Mark the custom instruments for intra-day monitoring to retain real-time collected historical data for charting.
