2. A market in which prices are in an upward trend.
3. Refers to a market on a downward trend.
4. The period at the end of the trading session. Also used to refer to the last price a stock sells for on a given day. The previous close is the price a stock closed at the previous day.
5. A fee that covers the broker's charge for processing a transaction. It is either added to the amount you pay when you buy securities, or deducted from the amount you get when you sell.

For example, if you want to buy ABC Company stock at no more than $20 per share and it is selling at $25 now, you can place a limit order for $20 per share. Some brokers charge a higher commission for limit orders than for market orders.
