Pre-market trading is buying and selling listed stocks before the official U.S. regular session (9:30 a.m. – 4:00 p.m. Eastern Time). It happens on electronic venues with different liquidity and rules than main session trading. It matters because news, earnings, and global flows often land when that main session is closed, and prices can move before many participants are at their desks.
If you run or use a brokerage platform, pre-market is also a product and risk topic: order types, risk warnings, and how quotes are shown need to match what your broker supports for liquidity, routing, and session rules.
So How Does a Broker Actually Work?
In simple terms, a broker’s system allows a client to place an order, and then that order is executed in the market. On the outside, the process looks extremely easy – you tap a button on a platform and your trade appears in your portfolio. But on the other side of the screen, several things happen instantly:
- the broker’s platform checks if you have enough balance
- it sends the order to a liquidity provider or internal system
- the price is confirmed
- the position opens within milliseconds
They also make sure everything is legal – identity verification, anti-money laundering checks, storing transaction history.
And of course, they make money. Brokers earn from spreads (the tiny difference between buy and sell price), commissions per trade, overnight swap fees or fixed service fees. Real estate brokers earn commissions from property sales, insurance brokers take a percentage from the policy provider.
Different Types of Brokers (Not Only in Finance)

Broker vs Dealer – Why It Matters
People often confuse these two. A broker connects two sides and earns a fee for helping them. They do not take financial risk. A dealer, on the other hand, buys and sells assets themselves and makes profit from price differences.
For example, a forex broker gives you access to the market and charges a small spread. A car dealer buys cars first and then sells them to you for a higher price. One connects, the other owns.
