Q&A on HFT of Microsoft Windows .NET vs C++ on Linux, and MongoDB NOSQL software vs FPGA hardware for ultra lowest latency

From a member through Linked In:

Hi Bryan, I have a few questions:

1) Why use VC++ and C# .NET/Windows? C++ on Linux is what HFT firms use. Name one that uses Windows for anything but the Front End.

–> Lots of hedge funds in UK use .NET. This has been confirmed by many sources of quant contacts I know. I worked at CPP-IB as they were a .NET shop.

2) A custom in-memory database written in C++ would be much faster than almost anything on the market. A relational DB like MYSQL or NOSQL DB like Mongo would be much too slow for HFT.
Any thoughts on this?

–> It all depends on how you manage your memory, data types, and programming patterns you use. The one system I know of is using MongoDB which is incredibly fast which does real time analytics. Either way, FPGA is the lowest latency for HFT so any software methods are  secondary.

3) Have you ever thought about contacting Mathworks and asking them
to give your membership the ability to purchase the matlab student edition? They get some of the best free advertising from you. You could also allow them to advertise on your site.
–> They will offer only through accredited universities. I will be working on Mathworks on other events.
