What is a quantitative (quant) trader?
A quantitative trader is a professional who trades financial instruments within the confines of a quantitative trading strategy. These traders use mathematical models and statistical techniques to make informed decisions about when to buy or sell securities.
Quantitative traders typically work for large banks, hedge funds, or other financial institutions. They often have backgrounds in mathematics, physics, engineering, or computer science. Many quantitative traders develop their own trading algorithms and models.
