Floor Trader

A floor trader is a person who buys and sells for their own account, physically standing on the trading floor of an exchange, rather than trading from a desk or through an online platform. Historically this meant being on the floor of a stock exchange or a futures/options exchange, wearing a colored jacket, using hand signals and shouted bids and offers to trade directly with other floor traders in what is called open outcry.

The mechanics were simple in concept: a floor trader would take positions based on order flow they could see and feel around them — the crowd getting excited, brokers rushing in with big orders, prices moving in a pit — and try to profit from very short-term price swings, often holding positions for seconds or minutes. Because they traded their own money and not client orders, they are distinct from floor brokers, who executed orders on behalf of customers for a commission. A floor trader's edge came from proximity: being physically present let them react to information and order flow faster than anyone off the floor.

The nuance that trips people up today is that open-outcry floor trading has largely been replaced by electronic trading on most major exchanges, so the term now mostly survives as a historical or specialized reference. Some exchanges, notably parts of the futures and options markets, retained floor trading longer than equities did, but the population of true floor traders has shrunk dramatically as trading moved to screens and algorithms. People sometimes loosely use "floor trader" to mean any in-house proprietary trader at a firm, which is not quite accurate — the term properly refers to physical floor presence.

It's also worth separating floor trader from "local," a term used in futures pits for an independent floor trader working purely for their own account, as opposed to firms with multiple floor employees.
