Exchange Rates: Stock, Index and Quote

Next, we've got the issue elements, which contain all exchange data. The primary issue for an <Organisation> (root) is indicated by <PrimaryIssue>.

NoteThe <PrimaryIssue> element is only a reference; the actual data is stored within the forementioned elements, which we will investigate in more detail here.

First, we'll start with the description of <Issue>.

• <Organisation>
  • <Issue type="..." exchange="...">
    • <Name/>
    • <Quote date="..."/>
    • 
    • <Ticker id="..." type="..."/>
    • 
  • </Issue>
  • 
• </Organisation>

The only complex element here is the <Quote> element, which contains a lot of child elements: <Open>, <Close>, <Previous>, <Last>, <High>, <Low>, <Ask> and <Bid>. Often, most of these elements contain little or no data (see Data Stripping: How the TBXDS Engine Compacts Your Data). Note that the issue's currency is statet at the <Quote> level.

Although the structure of <Quote> may seem intimidating at first, it's actually quite simple to work with; see the description of <Quote>. Likewise, the structure of <Ticker> is quite straight forward as well.

Roughly speaking, the structure of <Quote> is

• <Quote id="..." date="...">
  • <High/>
  • <Low/>
  • <Open/>
  • <Close/>
  • <Last/>
  • <Previous/>
  • <Ask/>
  • <Bid/>
• </Quote>
