High Frequency Trading Explained

 What is high frequency trading?

High-frequency trading, also known as HFT, is a method of trading that uses powerful computer programs to transact a large number of orders in fractions of a second. ... Typically, the traders with the fastest execution speeds are more profitable than traders with slower execution speeds.

If you're an average human being, your eyes take around 400 milliseconds to blink once. High-frequency trading is a kind of market activity that moves in less than one millisecond to spot and take advantage of an opportunity to buy or sell. It happens through trading algorithms, programs that determine how to trade based on fast-moving market data.

The kind of profit opportunities that high-frequency trading looks for aren't the things most investors ever think about. They're not betting that technology companies will see their profits grow more quickly than expected, for example, or that a recession is coming.

Instead, they're looking for tiny opportunities for arbitrage. Imagine that, at precisely 10:30:01.01 AM, a share of Bank of America's stock was trading at $16.02 on the New York Stock Exchange - but it was $16.04 on a smaller exchange called BATS. A high-frequency trading computer might spring into action by buying up shares of stock on the New York Stock Exchange and selling them on BATS. To make money this way you need to move super-fast, because the opportunity could vanish at any moment.

About Me I have done my B Tech in Computer Science and Engineering from IIT Bombay. I too faced a similar dilemma and chose to finally go with doing a job in an HFT. Work culture The work in HFTs is hectic if we compare it to software companies but it’s interesting too. It’s a fast-paced industry and you are required to work quickly on things that the company wants to be done in order to reach its goals. You are required to give a lot of time to some ongoing problem that the team faces in trading which might be hampering live trading. And once the team finds a solution, it is brought into production rapidly. Comparing this with the work in a typical software firm, you are generally assigned some tasks with their correspo
