Excel VBA - industrialisation...Part Fourteen "Enumerating Excel.Model"

Excel 2013 included a number of changes - one of the big changes is the addition of Excel.Model.  In essence, this allows the user to treat data within the Excel spreadsheets as though it is contained within database tables. 

Solace Systems & Node.js Market Data Terminal

We have looked at market data terminals and middleware.  One of the challenges of building a modern web browser based application is that there is a requirement to push JavaScript to the client to provide an interactive user experience and almost always a requirement to serve up real-time streaming data.

Fixed Income: New market for Corporate Bonds

A topic we have covered before is the evolution of the market place for Corporate Bond trading - "Matching engine for corporate bonds?".  Since the demise of Lehman Brothers we have seen the banks pull back capital from the corporate bond flow trading business and a subsequent drastic reduction in liquidity.  This post is a modest proposal for the structure of how a new Fixed Income market could work.

Sell-side FIX reference implementation (not low latency)

This post will cover a reference implementation of a FIX ecosystem for a reasonable size sell-side organisation. The target here is not a low latency environment.  The trading ecosystem that is suited to this reference implementation is a hub and spoke model, where a sell-side in a region runs connectivity out from a central hub to the regional exchanges (or SEFs, ECNs, FX Hubs etc.).

Excel VBA - industrialisation...Part Ten "Enumerating COMAddins"

Excel VBA - industrialisation...Part Eight "Enumerating RTD Servers"

An Excel RTD Server is a hybrid push/pull mechanism that can send data into Excel in something approaching real-time. If you are not familiar with this technology, you can find instructions on how to build one on this blog at:

Excel VBA - industrialisation...Part Nine "Enumerating DDE Servers"

A DDE Server is an old technology that is still used by a number of vendors to push real time data into Excel.  It has mainly been replaced by RTD but is still in use by many firms for internal applications and for some legacy applications.  In some quite particular use cases DDE outperforms RTD and so it will remain in use for some time yet.
