Almost a year ago, the first version of http://fixparser.targetcompid.com was released. Then, as now, it was the most user friendly and beautiful way to quickly comprehend FIX messages. Since then, several features have been added, including a few in response to user requests.

A few minutes ago, a brand new version of the app was released. It is almost completely redesigned, front to back with complete focus on making your FIX life easier.

Let's start with a non-feature. The new version adds a note "Your FIX data is never sent to any server, it stays private and local to your machine." This was always true, just wasn't posted. FIX parser is a completely client-side app. Once you've loaded the web page, you can even disconnect your computer from the internet and the app will continue to work.

On to the new stuff.

Timeline view now shows relevant details, such as symbol, side quantity and reject text right next to the event type itself. This feature alone doubles the utility of FIX Parser.

What's the best way to double the usefulness once again? Show which events are related to each other. Click on a New Order and you will see fills related to it. Click on a session Reject and you will see the referenced event. Making simple, what used to be a pain.

The look and feel has been updated. The colors contrast better, there is less noise and the focus is squarely on the events. Use the app on your desktop, tablet or even your phone. It works beautifully.

Finally, a great deal of thought and love has been put into the code behind the app. The parsing logic has been completely rewritten to process data much more intelligently.

For the technically minded, the server side story is very interesting in its own right. There is no server side code! The app is served off Google's cloud storage. Naturally, FIX messages can contain sensitive information, which is why no FIX data is ever sent outside your computer. There is no server to send it to!

The first version was also a labor of love and still lives at http://fixparser.targetcompid.com/v1.0 . This version improves usefulness by an order of magnitude.

There are several more ideas floating around in our heads. If you have an idea, a request or even a complaint, please send a note to fixsanity@targetcompid.com
