QuoteLink.NET releases 3 applications

  • A new version ql.0.80.* with MB trading support
  • quoteLink for Yahoo finance - A new RTD server application dedicated to Yahoo finance streaming quotes
  • quoteLink for DTN IQFeed - QA new RTD server application dedicated to IQFeed

ql.0.80.* adds support to MB Trading. It does not have otherwise major changes. All users may thus update.

I decided from now on to release targeted applications addressing specific features instead of changing a single program that does it all. The first two applications following this paradigm are now available:

  • The Yahoo application aims to get the most of quotes from Yahoo finance.
  • The IQFeed application optimizes speed for quotes and series. It has been tested with 1,800 quotes and 500 series

As usual All applications are RTD servers and do not interfere with Excel otherwise. They are meant to be used together in spreadsheets.

They are selected by different server strings respectively ,"quotein.rtd", "iq", "ya"

This means "=RTD("ya",, "CSCO", "LAST") is a valid formula if you have the Yahoo application installed.

The new installer is able to install and manage these new applications.


There are two ways of using IQFeed. The usual one using ql.0.80.* and which I recommend for options chains and the new one using the new RTD server which targets quotes and series.

They can be used simultaneously.

February 3 th, 2015:

  • ql.0.79.21
  • Minor changes; Documentation links

January 16 th, 2015:

  • ql.0.79.17
  • OX feed review - minor changes

July 22 th, 2014:

  • ql.0.79.15
  • corrected minor problem in the 'add feeds' dialog

July 3 th, 2014:

  • ql.0.79.14
  • change of formula syntax for complex requests see box below
  • corrects some bugs on the wizard menus (when right clicking the symbol was not correctly read from the spreadsheet)
  • adds a new futures example
  • IB portfolio corrected types (some values were character strings)
  • strike field was missing in the positions list
The version ql.0.79.* introduces a new system of worksheet requests.
This change will affect users that create their own series spreadsheets or customized options chains.

It is straightforward to convert the old requests to the new format. However and to prevent problems, do not update to the new version on a rush.
(Note that you can always rollback to 0.78.83 using menu Support > Switch Version in case of trouble).

Other than that there should be no compatible problems as the changes were minor

More on the new worksheet formulae

The reasons for this change are:

  • New system is more intuitive (the old system was confusing at times)
  • Higher flexibility when combining fields
