Real-time stock quotes reflect current trading activity and are crucial for traders to make profitable trades. Delayed prices are available but may not be as useful. Bid and ask prices determine supply and demand, while the spread represents commissions. Electronic exchanges execute trades faster and get the best price for investors.
Live stock quotes are real-time prices that reflect the trading taking place in the stock market. A stock price includes a monetary value coupled with a directional change, up or down, that represents a stock’s position since its last trade. If a stock trades higher, there is buying activity in that stock, while a downward movement represents a selling action. At the end of a trading session, there is a closing price of the stock that determines where the stock will begin trading the next day.
An alternative to real-time stock quotes are delayed prices with a delay of up to 15 minutes. A ticker tape running along the bottom of a television screen on a corporate network might include delayed pricing, although users can get real-time data over the Internet by subscribing to certain services. Live trading is especially important for traders on a stock exchange whose livelihood revolves around placing bets on rapid, incremental changes in a stock’s price.
Investors, of course, are looking to enter a stock position at the lowest possible price and sell a stock at the highest value for a profit. Real-time stock quotes can be the difference between profit and loss. If an investor is about to enter a trading position, for example, but notices from live stock quotes that the investment is falling precipitously in value, he may decide to reconsider his purchase.
There are components that determine the value of stock quotes in real time. The bid and ask price represent the supply and demand in a stock. A bid price reflects the most recent price investors were willing to buy the stock, while the ask price reflects the amount investors were most recently willing to sell the stock. A spread is the difference between the buy and ask price and represents the commissions paid to a trader or market maker who facilitates buy and sell orders.
The importance of real-time stock quotes in financial markets surrounds timing. Traders are better able to execute profitable trades with the most up-to-date information. The exchange where the trades are made also plays on the timing.
In the United States, the Nasdaq stock exchange is an all-electronic stock exchange where computers are responsible for executing buy and sell orders. The alternative to an electronic exchange is an open protest system, where human trading specialists manually match buyers and sellers in one action. The high-speed electronic models of the exchanges are credited with executing the fastest trades and ultimately getting the best possible price for investors. Some exchanges, such as the New York Stock Exchange Euronext, which is a combination of two of the largest exchanges in the United States and Europe, adhere to a hybrid model where there is both electronic trading and an open protest system.
