Hello All. Some of the direct and indirect comments about QuoteIN above are misleading. It seems very easy to write a RTD server but the problem is not only RTD itself, the problem is much more to have a fast and flexible framework that connects to the remote servers and that can exploit RTD potential. This is what QuoteIN addresses and successfully solves.
To clarify what QuoteIN is and what its subscription pays:
The first thing to know is that it consists of QuoteIN add-in (which is the most popular) plus QuoteLink Tools which is the module that handles the data connections to the servers and offers it through the APIs
The data comes either
- directly from remote servers
- through QT streaming API
- ( and from next version through a new DDE Gateway )
The direct access to remote servers is the main mode and is by far the fastest since it connects directly to the servers. It avoids using intermediate applications and it is the one that fully exploits RTD possibilities. Also it is much simpler since there is only one application to configure which is Excel itself! The others are limited by all the applications in the middle but are handy because many more sources are available.
- RTD access in Excel (XLL for older Excel 97/2000)
- built-in native code options pricing functions using black-scholes and binomial methods and implied volatility
- include direct dump of intraday data directly from the server or collected locally which allows to write custom indicators/studies and produce charts with the results.
- All features are available in .NET and COM interfaces which can be used from within Excel or to produce stand alone applications
Speed and flexibility are the common design goal to all features here are some numbers:
QuoteIN RTD running on Excel
- 2,000 streaming in Excel
- more then 10,000 refreshing snapshots â kept within 1 minute
Stand alone applications build on top of the COM and .NET are not bounded by those limits since they donât use Excel but use only the framework libraries.The framework is very fast you can create an application on .NET that compute on all NYSE! (This kind of solution is available only using broadcast feeds and as a custom solution)
The framework is multithreaded and supports automatic recovery/reconnection and has a common cache (several applications share the same connections to the remote servers)
Though QuoteIN and QuoteLink Tools are available and many users are using it is not yet considered feature complete (hence the < 1 version) on the pipeline are more analytic possibilities, Level 2 , News.
About the comment on to the latest version: All published versions are tested the version number less than 1.0 simply means that not all the features planned are not there yet. (any unstable versions are labeled Beta when they happen)
Thanks for letting me post this clarification somewhat long here.
