What is High-Frequency Trading (HFT)?
High-Frequency Trading (HFT) is a form of algorithmic trading that relies on executing a large number of orders at extremely high speeds. These trades capitalize on small price differences that exist for only milliseconds. HFT is used to enhance market liquidity and price efficiency.
What are Prop Firms?
Proprietary trading firms (prop firms) are private firms that trade financial instruments using their own capital rather than client funds. Unlike hedge funds or brokers, prop firms profit directly from market movements instead of earning commissions.
Why Do Prop Firms Use HFT?
HFT allows prop firms to:
- Make rapid trading decisions
- Exploit market inefficiencies
- Provide liquidity to markets
- Reduce risk through diversification
