Who trades the most volume in finance
How does trade volume compare between Asset Managers, Hedge Funds, HFT, Investment banks (S&T). What is the position size of each institutions trades? How do you see these institutions trade volume evolving over the next 5-20+ years?
I have heard HFT firms trade upwards of a billion per day on small arbitrage opportunities.
Any insight or sources you can point to are apprecitated.
