How much math and probability theory do you use in prop trading

Thinking about moving from a fundamental L/S HF seat at a multi-strat to prop trading - I like trading more and making quick decisions / trading around events and earnings and am not a big fan of deep analysis that consumes a lot of time.

I’m def not a quant however, so wondering how much math and probability theory, etc in the interviews do you actually use on the desk?

Based on the most helpful WSO content, math and probability theory play a significant role in both the interviews and the day-to-day work of prop trading, especially at top firms. Here's a breakdown:

  1. Interviews:

    • Prop trading interviews often start with math tests focused on mental math and problem-solving. These tests are designed to screen candidates and have a high failure rate.
    • As you progress, the interviews become increasingly quantitative, involving probability and statistics problems that can resemble national math competition-level questions.
    • Structured preparation, such as practicing mental math (e.g., using tools like http://arithmetic.zetamac.com/game?key=a7220a92</a">Zetamac) and studying probability, is essential.
  2. On the Desk:

    • While you don't need to be a full-blown quant, a solid understanding of probability and quick decision-making based on statistical insights are crucial.
    • Many successful prop traders have strong math backgrounds or have honed their skills in competitive mathematics.
    • Coding skills (e.g., Python) are also highly valued, as they help in analyzing data and automating strategies.

If you're transitioning from a fundamental L/S HF seat, you might need to brush up on these areas to stay competitive. However, your ability to make quick decisions and trade around events could align well with the fast-paced nature of prop trading.

"I'm not a big fan of deep analysis that consumes a lot of time" I mean this is pretty typical for almost any human. Do you mean you don't like to do difficult work? Do you like to do easy and quick analysis?

To answer your question though, yes plenty. Based on friends at prop shops, esp probability theory
