Sanchit

Trader, Maths and Computer Science

What’s your job about?

Citadel Securities is a market-making firm, which means we constantly quote prices to the market on all the assets we trade. Our primary function is to provide liquidity in the market which allows participants easier access to the markets for when they want to trade.

I’m in the options team and we trade options on both stocks and the indices across different markets in the APAC region. As a trader, I spend most of my day on monitoring the trades we do and how the market performs in general. The main role of a trader is to manage your positions by adjusting pri…

Software Engineer, Chemistry

What's your job about?

Citadel Securities is a global market maker and I am a software engineer that works with the options market-making desk to build and maintain components that form part of a real-time trading system.

I work directly with traders and quantitative researchers on projects designed for new trading strategies or business plans. I also work with them to upgrade and improve existing technology. There is a large variety of work that I’m involved in, including capturing data for later analysis, serving user interfaces, managing user parameters, trade reporting and reconciliation etc. It really is a ‘full stack’…

Trader, Math & Aerospace Engineering

What's your job about?

I’m an options trader at Citadel Securities, where we take on the role of being ‘Options Market Makers’. This means that we have a contractual obligation to exchanges to continually provide prices at which we will buy and sell securities (options in my case). Unlike a lot of market participants who chose the exact trades they want to do, we specifically don’t get to do that – we always take the opposite side of what others want to do.

My job is primarily about what happens during market hours. When the exchange I trade is open, I’m pretty glued to my trading monitor; adjusting our pricing in o…
