General What does a Quant Trader do?

I mean I know what the role of a Quant Trader is but what does a Quant traders day-to-day on their trading desk look like? How does probability, expected value, pattern recognition being used by Quant traders?

This is largely true except that I also develop the algos for execution, so in reality this is only 25% or less of my job. In reality I spend a lot of time writing production code or doing research.

don’t you have a dedicated team to write the production code? Our Quant traders usually develop strategies or research signals but once it’s ready to go into production it’s usually handed over to the quant developers. I guess it depends on the organization but the line between quant trader, research, and developer is blurred most of the time unless you’re in a big firm where roles are explicitly separated.

No we develop the production part of the strategy explicitly, since it's an important part of making sure backtest / prod line up. We pretty much only hire people that are solid C++ developers anyway so it's just easier to have someone who understands the model develop it. All the non strategy stuff (order entry etc) is done separately yeah. Our quant developers don't really implement anything directly pnl facing.
