===== Tick data RTD server =====
 
QuoteLink is able to download past tick data from the server site and to collect current ticks.
The data  maybe accessed using the historical data formula with  0 as period. The data collection is done by the underlying QuoteLink platform not by Excel and all ticks are collected.

Write a series definition formula in a cell:

  =SDF(<symbol>, 0, <days to retrieve>, <feed>)
  
Write cells that refer to that SDF:

  =S(<reference to a SDF>, <order>, <field>)


^parameter ^description ^
|symbol| symbol of ticker|
|field| the field to get it may be one of these: VOLUME, OPEN, HIGH, LOW, CLOSE, TOTAL|
|order| tick order ( < 0 before starting > 0 after starting|
|feed| the feed to use|

The tick order are always negative values.
