Hello everyone!

My name is Igor Pyshkin. Throughout my academic career, I participated in a lot of programming and math competitions: I am the 2016 ACM ICPC World Champion and competed in the onsite finals of the Facebook Hacker Cup, Google Code Jam, and TopCoder Open. After completing my degree, I transitioned into a new field — high-frequency trading (HFT).

Four years ago, I founded my own HFT fund — Order Capital. Since then together with my colleagues I have been working really hard to reach the highest levels of the HFT industry. Launching this contest on Codeforces is quite special to me, as it is our first contest on the platform as a company.

I would like to thank the Codeforces team and everyone involved in the round preparation. Our internal testing team found the problems quite interesting, I hope you will enjoy them too.

We’ve prepared some cool prizes:

• Top participants will receive cash awards.
• Plus, several random participants will get surprise merch boxes.

Below you will find information about Order Capital. We are hiring and would be happy to discuss opportunities for professional growth with you.

Based in Dubai

We’re a place where:

• Olympiad minds feel at home
• Engineering culture > corporate process
• Big ideas are valued and debated

We’re looking for:

• C++ Engineers (low-latency, high-performance)
• ML Infra Engineers (Python / C++)
• Research Engineers with strong algorithmic skills

We loved working on this round and hope it’s fun for you. If you’re curious about what we do at Order Capital — we’d love to hear from you! Just follow the link and fill out a quick form.

This is our debut contest — and we’ve worked hard to make it fun, fair, and memorable. We hope you’ll enjoy the experience!

GL & HF!
