How We Work on Design Use Сases. Symbol Library

May 3rd, 2017 No comments

dxMobile is part of our extensive finance software product line gathered under one brand. It was launched on web, desktop, and mobile platforms (both iOS and Android). It is a complex product that boasts rich functionality for financial analysts, professional traders, and researchers. It provides the ability to trade, use analytics, charting and newsfeed for different vendors and brokers. All products in the line have their unique color palettes and style guides. Designing mobile apps, we aspire to maintain the entire functionality of the base platforms (web and desktop). As one could expect, a transition of massive web components to a mobile platform would require a very thorough adaptation. Needless to say, it is crucial for us to keep the platform up to system guidelines and modern trends. We have been designing this app for a couple of years already so we have faced and solved numerous different cases during this time. This article is an attempt to describe one of these cases on our Android application. Read more…

What is the customer not aware of when developing trade application design?

April 19th, 2017 No comments

Nik Slezkinsky, Head of UX Design Department at Devexperts, shared his vision on building award-winning trade application UI’s

Interviewer: Can you describe the Devexperts Design Team working process?

Nik: There are two ways to develop a UI. The first one is when we are free to create a product from scratch. Starting from scratch is easy, as we have full control over the implementation process and the result. In the second case, clients provide us with logos, colors, and maybe some more guidelines, so front-end terminals design is built under certain constraints. Here the story is unpredictable every time as we may have some challenges to overcome. For example, a client might want Read more…

How to build a successful iOS application from Java code in two months

The challenge

Enjoy a challenge? Our mission in early Spring 2016 was to develop a live prototype of the OTC flex-options trading application in a very short space of time. Join the Devexperts Mobile Development team on a journey of discovery as we set to work at finding the ultimate solution.

In a not so distant past it used to be the norm to essentially perform all trading operations manually – with a phone in one hand and a spreadsheet with your positions in the other. The teams’ overall goal was to automate current workflow allowing traders to monitor their options portfolio on the fly and simultaneously analyse risks.

Phase one of this exciting project involved developing a desktop application and a mobile solution – iPad app. Working closely with designers and the UI/UX team to implement as much functionality as possible, the overall achievement of delivering this comprehensive product on time was impressive. The project started in early April and had to be completed by the designated date in late May – and not a single day later. In total, the team had only had 6-8 weeks pure development time.

How Requirement Patterns can benefit your business

September 11th, 2015 No comments

Software companies increasingly have a variety of different projects to manage. Sometimes these projects are similar to one another, or at least they have some common functionality, sometimes however they are not. Overall, the majority of projects business analysts and development teams work on contain very similar (if not the same) portions of functionality, defined in the project scope.

Let’s not forget about high rotation of people, not only between different projects, but also between different companies. Not everyone involved will necessarily have a deep knowledge or understanding of the product functionality or even the business area the project is related to. For new-coming analysts, the problem of understanding the business area could be easily resolved by Read more…

We will forever cherish the memory of you, Artem. You will be greatly missed.

ArtemColleagues and friends,
Our close-knit company has suffered a tragic loss. On Saturday, our friend and colleague Artem Kozyrev, a warm-hearted and inspiring person, fell through the ice to his death.

Artem was one of the co-founders of the company, the person behind the first versions of the TOS and Thinkpipes platforms and a great source of expertise on option trading. Artem was a kind, wise and open-minded person with a positive attitude. It was great pleasure to work with him because of his exceptional friendliness, outstanding intellect and knowledge. He was always determined to do the right thing the right way.

Artem was a loving husband and father of two young children.

GUI Automation Difficulties.  When marketing collides with real life. 

March 12th, 2015 No comments

mvc_pic.001 Usually, it is good practice to automate  any kind of routine. In testing,  automation is vital. It helps decrease  costs, makes testing tasks faster, and  improves efficiency of your staff. It is a  “no-brainer” to think about automating  different testing tasks, especially when  reading marketing materials or listening  to a sales presentation of a “leading-  edge-premier” robot software. Those reports are usually based on success stories from the world of the most complicated user interfaces – CAD software, graphics software or maybe some examples of extremely complex but good web design. Moreover, usually, these reports are true. But you should think carefully before starting a GUI test automation project. In many areas of software development, GUI automation is not so easy and obvious, and your entire automation project can quickly turn into disaster, in spite of the visual attractiveness of the tools.

Have a nice reading!

Hi everyone!

My name is Nick and for those who are not aware, I’m leading the team responsible for the “dx” user interfaces and user experience. We design both Devexperts own “dx” applications, and white-labeled applications based on “dx-technology”.

3 easy steps to improve quality of your concurrent programs

February 12th, 2014 No comments

Weinberg’s Second Law says that if builders built buildings the way programmers wrote programs, the first woodpecker that came along would destroy the civilization. In practice it means that any software has to be tested very carefully to fix bugs in it in the earliest stage of its lifecycle.

Rapid expansion of multicore and multiprocessor systems makes software developers write parallel programs to use system resources as efficiently as possible. And here another big hazard is hidden – errors, related to incorrect usage of multiple threads of execution. On big production servers it’s a much bigger threat than it seems, because the program code is physically executed on different cores or processors, and concurrent issues arise in their full capacity. Most well-known problems of such a kind are deadlocks and data races. All concurrent issues are hard to detect manually or by testing, because their nature is essentially nondeterministic. Data race detection is an especial issue, because the effect of their occurrence may become apparent much later. When a data race occurs, global data are corrupted, but the application itself doesn’t halt, it continues to work with incorrect data, and who knows when one would notice it. Data races may be really dangerous – e.g. data race was the cause of accidents with Therac-25, the radiation therapy machine, that gave massive overdoses of radiation to six patients. Also data race was one of the causes that led to the Northeast blackout of 2003 that affected more than 50 million people in the US and Canada.
