Some exchanges are physical locations where transactions are carried out on a trading floor, by a method known as open outcry. This method is used in some stock exchanges and commodity exchanges, and involves traders shouting bid and offer prices. The other type of stock exchange has a network of computers where trades are made electronically. An example of such an exchange is the NASDAQ. Stock Investing Disclosure
The most common order types: market, limit, and stop (see my guide, Best Order Types for Stock Trading). Market orders buy or sell immediately at the current best market price. Limit orders only buy or sell these shares at, “$xx price or better”. Lastly, stop loss orders are combined with a market or limit to trigger once $xx price hits. For new investors just getting started, I always suggest just sticking with market orders.
