a. Market Order As the simplest and most common stock trade, the market order is carried out by placing an order to buy and sell stocks at the current market price.b. Limit Order The limit order takes place when you place an order to make a trade when it meets your maximum buying price or minimum selling price. Do take note that this order may never be executed when your criterion is not met.c. All-or-None OrderStocks may not be available right away, and what happens is that you pay different prices for different portions of the order. An all-or-none order requires a trade fulfilled when there are sufficient stocks. Otherwise, the trade is simply not done. d. Fill-or-Kill OrderAs a strict type of order, the fill-or-kill order requires that a transaction meets the criterion and is wholly executed immediately, or else the whole order is canceled. e. Immediate-or-Cancel Order It is a close cousin of fill-or-kill. The difference lies in the fact that immediate-or-cancel order allows partial execution as long as the criterion is met. When succeeding portions fail, the remaining order is cut and canceled.f. Stop OrderOnce the stop price is met, the stop order is converted to a market order. This means that a transaction is executed at the current market price. g. Stop-Limit OrderAlmost like the former, a stop-limit order is converted to a limit order once the stop price is met. Thus, the trade is carried out when it meets the minimum selling price or the maximum buying price.h. Short Sell OrderSelling short a stock is done when you think the stock price will fall. A certain stock may be temporarily inflated, so you borrow a number of such stocks and sell it at the inflated price. When the price falls, you do the next type of trade—buy to cover order—to complete the short sale. i. Buy to Cover OrderThis is done in tandem with the previous type of order. When the price does fall, you now have to return the borrowed shares and purchase them. The money left over from selling them at the inflated price is your profit. j. Day Order and Week OrderThis type of order pertains to when a trade can be executed. A trade is a day order when it is only good until the end of the regular day. If not executed by then, it is canceled. Similarly, the week order is executable for a week. k. Good-Til-Canceled OrderThis is another order type that pertains to when a trade takes place. A good-til-canceled order remains executable unless it is done or it is canceled. The risk of this is that you might forget about it. Plus, you pay more trade fees if it is partially done on different days rather than when it is completed in a single day. l. Trailing Stop OrderThis is similar to the stop order, except that the stop price is expressed as a spread of different points or a percentage of the current market price. m. Bracketed OrderA bracketed order is just like the trailing stop order but it goes further by setting an upper limit as well. When the upper limit is met, the stock is sold.
