FIX Parser has been serving the trading community for nearly 14 years. This app has been so successful that there are multiple sites inspired by it — and one which is simply a clone :)

Since the first release, almost a decade and a half ago, there is been one major overhaul. Today we are releasing another.

The look has been modernized, and a handful of new features have been added:

• There is a tag lookup in the top right-hand corner, which makes this app a handy FIX reference. Ironically the original version had it, but it was removed to simplify the UI — many of you asked for it back, so here it is.
• You can filter the view to only specific order IDs, Comp IDs, symbols, message types, and more. You can also exclude those same entities. Either way, you can focus on exactly the messages that matter to you.
• The mechanism to share encrypted FIX logs with clients or colleagues has been simplified.
• You can add or remove columns to focus on the fields that matter to you.
• Large messages are parsed significantly faster — the difference will surprise you.

This is just the beginning of broader changes coming to the site — some on the public app, some available to clients running it behind their firewall, and some extending it into interesting new use cases. More on those soon. Let us know if you want to be part of an early access cohort.

Your feedback is what has kept this among the most loved web apps on Wall Street. Bug reports and feature requests drive everything, and fan emails are always a pleasure to read. As many of you have noted, yes — we know this site has been copied. We take it as a compliment :) Please keep reaching out at fixsanity@targetcompid.com (a nod to the site's original name).
