My First Patent Application

My friend William just alerted me that our patent application has been published on the USPTO website. This dates back to our days at TT and it’s titled “System, Method, and Tool for Synthetic Order Recovery”. While William already has a few patents in his pocket, this one is my first 🙂

This patent document relates to a system, method, and tool for synthetic order recovery. In certain embodiments, an exemplary method includes detecting a server event associated with a synthetic order server identified by a synthetic order server identifier, wherein the synthetic order server is in communication with the recovery tool; determining at least one active synthetic order associated with the synthetic order server identifier; determining a child order status for each child order related to the at least one active synthetic order, wherein the child order status includes an updated child order quantity since the server event was detected, and wherein each child order is associated with the synthetic order server identifier; calculating an updated synthetic order quantity for each of the at least one active synthetic order and based on the updated child order quantity; generating a recovery package including the at least one active synthetic order and the updated synthetic order quantity; and communicating the recovery package to the synthetic order server associated with the synthetic order server identifier.

TT Mobile showcase

My friends at TT are really busy trying to get the mobile clients out the door and into production. TT’s twitter account is buzzing with all kinds of photos and videos. I am really happy and proud of how far my apps have come. The end result is looking beautiful and I am sure the end-users will be delighted by both the design and functionality.

I really enjoyed working on TT Mobile, as it presented a very unique set of challenges. How to effectively push price updates over potentially slow cellular connections? How to ensure users don’t accidentally place trades (butt trading anyone)? And how to effectively integrate with the rest of TT’s eco-system? I think the team did a splendid job and the apps are rock solid. One disappointing fact is that both Android and iOS apps could have been released over a year ago, had we chosen to re-use logic. There are ways to write the code once, and use it verbatim on multiple mobile platforms (naturally the look-and-feel needs to be done separately, so that the app feels “native”). I have long argued with the executives and advocated for shared business logic, since it seemed like a no-brainer.

  • Shorter time-to-market. In today’s fast-moving world it’s imperative to be there first.
  • Lower cost of development.
  • Less bugs.
  • Parallel releases on multiple platforms.
  • Lower long-term maintenance costs.
  • Less testing effort.

Other companies are not as short-sighted and have long recognized the benefits of writing the common logic once, instead of re-implementing it for every platform. Xamarin has their cross-platform C#. Google is pushing Java with its ability to share code between Android, iOS and the web. Dropbox uses C++ for shared logic. RemObjects has their cross-platform Swift. Not to mention frameworks like Flash and Cordova. I still cannot believe that the decision makers would rather have us maintain two separate codebases, but I guess you need to be good at engineering to comprehend the benefits.   

On a positive note, I am extremely pleased with the aesthetics of TT Mobile apps; graphical design and usability are essential. Nobody wants to use an app that looks “f-ugly” or that feels cumbersome. Folks at TT spent countless hours doing usability studies and polishing the design. Trust me – a lot of love went into making of these apps. They look awesome, they are snappy and I really hope you’ll enjoy them 🙂

To my friends at TT

Hi Everyone,

I would like to thank each and every one of you, who have been calling TT a second home for all these years. We share many great memories: our outings, team lunches, water cooler talks, as well as simple, honest, everyday work. You guys have touched my life, and I will cherish these moments forever.

The greatest asset of TT has always been its people, and I have been very fortunate to have worked and learned from you. You are the reason this company is the powerhouse it is today. I am proud of our accomplishments.

While I’m moving on to the next great thing, this is a small world and I hope our paths will cross again. I’m looking forward to staying in touch. My personal e-mail is filipfracz-=at=-gmail.com. Let’s also connect on LinkedIn.
I wish you best of luck in your future endeavors.

Sincerely,

Filip Frącz

TT Mobile available in Google Play

TT Mobile is now available for everyone to download from Google Play. It looks awesome! Great job, team! This version also added support for trading strategies written in TT SDK running on my AlgoSE server. Below is a screenshot showing child orders of SSE’s Time Sliced order. TT’s next generation Synthetic Strategy Engine (SSE) runs on top of TT SDK and AlgoSE server. SSE strategies are written by my good friend William Baker.

TT Mobile in Google Play

Today marks an important milestone. TT’s next-generation mobile trading app for Android has been deployed to Google Play Store. It’s still in pre-release and available only to beta testers, but we are getting closer every day. It’s very stable and usable. The overall look has deviated slightly from my original design, but I like it better this way. It’s a little bit more intuitive. Below are the main functions of the app so far.

  • Watchlist of instruments
  • Instrument-centric view of orders and positions
  • Trading from order ticket
  • Trading and order management from price ladder (MD Trader)
  • Order management screen
  • Fills and Positions
  • Forever Audit Trail

The users can input trades from order ticket and MD Trader, monitor orders, have a watchlist of instruments, inspect their positions and watch the forever audit trail. Not too shabby for a mobile app! Very full featured, especially when compared to what’s out there. The team did an outstanding job. Oh, and iOS app is coming along as well.

Solution to MacBook storage problems

At Trading Technologies we recently switched to laptop-centric culture. Our desktops got lugged away and everyone can choose what kind of laptop they would like to have. I was one of the pilot MacBook Pro users and I got mine over 18 months ago. It took me a while to get used to it, but it completely changed the way I work. It’s so easy to just grab a laptop and crash a meeting room with two other devs. This makes communication so much easier. Not to mention I can now work on the train. Every company should consider this!

Unfortunately my Mac came with only 256 gigs of storage. For a developer that’s not that much. Especially that I use a lot of OSs on many VMs. I asked our IT, and they listened. It came earlier today. LaCie external SSD with USB 3.0 and Thunderbolt. It’s a speedy ~250MB/sec.

 

I really had a lot of fun velcroing it to my Mac. What do you think? Geeky enough for you? 😉

8 years at Trading Technologies

I just noticed it has been a whole 8 years since I started working for Trading Technologies. I was hired fresh out of college and began my journey on May 15, 2006 (well, I did some consulting on the side before coming to ChiTown).

During my career at TT, I pretty much worked on everything the company has to offer.

I spent countless hours massaging our flagship X_TRADER product. I was a key player in bringing .NET into the program and integrating it with native C++ and MFC. This really made adding new windows easier (have you ever had to deal with Win32/MFC?!) and allowed for tight X_STUDY integration.

In order to achieve maximum performance, I completely rewrote the Time & Sales window. Both the stand-alone and one integrated into MD Trader. While working on T&S I learned a lot about grids and data virtualization.

Every trader who’s copying/pasting links to and from Microsoft Excel goes through my Link Manager. That was a very fun project which definitely provided a ton of value for our customers. There are thousands of traders who design their strategies in Excel spreadsheets and want their numbers to be shown on grids, charts, ladders and algos. And this works both ways – I allow them to copy cells from X_TRADER and insert them into Excel. The data flows flawlessly and everything just magically works.

Look ma! I has Excel linkage! (Click for larger image)

For fun I also added preview to the Color settings window, which finally made it usable.
I wrote so many things for X_TRADER that I actually lost track. Not to mention countless prototypes to fool around with new features. Definitely good times 🙂

 

I am the architect and author of TT API – our high performance trading API for Windows. It was a great few years designing and implementing all the different features. I certainly learned a lot. TT API lets you trade any exchange that TT supports, including Autospreader SE and Synthetic SE engines. You can really go to town. Just check out TT API samples on GitHub.

It’s also worth mentioning that internally our Algo SE server and ADL (Algo Design Lab) are both powered by my TT API.

 

Two years ago I was selected to start on TT’s future platform. The codename for it used to be “Nextrader“, but due to trademark conflicts a new name was chosen. I coined the name and designed many low-level communication and security details (EdgeServer-to-client path, authorization, protocols, etc) which are now the foundation of the new system. I also led and directed the client-side team.  The TT platform is written from the ground up using modern technologies. It’s optimized for speed. Trust me – you will feel it 🙂

In addition to web-based interface, TT Platform will ship with an Android mobile app. That’s another one of my babies. I designed the flow and general layout of the main screens for both phone and tablet form factors. Our in-house designer Kevin made them look awesome. I’m sure you will love it! Working on mobile is challenging, as it forces you to think from a different perspective and face a whole new set of problems. Limited screen real-estate, battery life, disconnect scenarios, butt dialing (or shall I say: butt trading) are all issues you have to deal with. I had a blast 🙂

I started writing iOS version of TT Mobile with my team, but I didn’t get too far (enough to master Objective-C). I was needed on the new Algo project. Currently I am working with Andrew Gottemoller on our next-generation trading API, which we internally call TT SDK. The plan is to allow our customers to hand-craft their algos and run them in our co-lo facilities for minimum latency and maximum speed.

 

TT SDK is lean. It is fast. Linux and plain C. It is powerful, yet feels delightfully simple.  In addition to C we will eventually provide wrappers for higher-level languages. I, naturally, already have a C++14 and Mono C# version going. Stay tuned!

 

As you see, I’ve been having fun. Trading Technologies is a great company, but its most important asset are definitely the people. Everyone is smart and easy-going. I made many good friends at TT and I’m happy to see them every day.
Let’s see what the future will bring 🙂
