Fields |
exchange exchange is the Aspen exchange identifier, a unique number assigned to the exchange by the feed parser.
The "exchange number" for each exchange on a particular feed is located in the <feed>xchg.txt file on the Aspen Server (see Apex Files). Exchange numbers vary from feed to feed.
The exchange number is available in an ASPEN_INSTRUMENT structure's exchange field after calling AspenRequest() with ASPEN_GetExchangeInfo.
tradingSession tradingSession is array of ASPEN_SESSION_TIME structures containing the open_time, close_time, and time_zone associated with each exchange. See ASPEN_INSTRUMENT for more information.
*name name contains a null-terminated ASCIIZ string that is the exchange abbreviation. Such abbreviations are commonly acronyms, like NYSE or NYS (New York Stock Exchange), or CBOT or CBT (Chicago Board of Trade). Exchange abbreviations vary from feed to feed. Consult your Server’s <feed>xchg.txt file for the exchange abbreviations in effect (see Apex Files).
*descs descs contains a null-terminated ASCIIZ string that is a textual description of the exchange’s proper, non-abbreviated name (New York Stock Exchange instead of NYSE). Exchange descriptions vary from feed to feed. Consult your Server's <feed>xchg.txt file for the exchange descriptions in effect. |
