Types of orders

There are a number of different types of order that clients may place with brokers.
  • Market order
  • Limit order
  • Stop order
  • Stop limit orders
  • Other orders


Market Orders (MKT)
Market orders are orders to buy or sell a contract at the current best price, whatever that price may be. In an active market, market orders will always get filled, but not necessarily at the exact price that the trader intended. For example, a trader might place a market order when the best price is 1.2954, but other orders might get filled first, and the trader's order might get filled at 1.2956 instead. Market orders are used when you definitely want your order to be processed, and are willing to risk getting a slightly different price.

Limit Orders (LMT)
Limit orders are orders to buy or sell a contract at a specific or better price. Limit orders may or may not get filled depending upon how the market is moving, but if they do get filled it will always be at the chosen price, or at a better price if there is one available. Here not time but the price at which trade is done is important.
In buy limit order one can buy at a price limit or lower i.e. in buy limit order one decides maximum price that can be paid to buy the price.
In sell limit order one can sell at limit price or higher, so here one decides the minimum price below which one cannot sell .
Limit orders are best when money at which is transacted  is more important than time of transaction.
For example, if a trader placed a limit order with a price of 1.2954, the order would only get filled at 1.2954 or better, if it got filled at all. Limit orders are used when you want to make sure that you get a suitable price, and are willing to risk not being filled at all.
The disadvantage of a limit order is that it may never be executed because the share price may quickly surpass the limit price before the order can be filled.


Stop Orders (STP)
Stop orders are similar to market orders, in that they are orders to buy or sell a contract at the best available price, but they are only processed if the market reaches a specific price called stop price.
It is of 2 types - buy and sell. 
Buy stop order - In case of buy stop order the investor protects a profit for short sale (Short sale is the sale of a stock not owned in the anticipation that the price of the stock will fail.) or in hope of making a gain, thinking that the stock is making the momentum.
Sell stop order is used to avoid further losses or to lock-in the profit that exists if the price of the share continues to fall.
For example, you have bought a stock at USD 100 and want to sell it as soon as it hits USD 105. So sell stop orders is used because a stop order becomes a market order once the specified price is hit. However, there is no guarantee that you will get out at the stop price (USD 105). You might get out above or below this price since you have no way of knowing which way the price will move once the stop price is hit.
Stop orders are processed as market orders, so if the stop (or trigger) price is reached, the order will always get filled, but not necessarily at the price that the trader intended. Stop orders will trigger if the market trades at or past the stop price, so for a buy order, the stop price must be above the current price, and for a sell order, the stop price must be below the current price.
Advantage of stop orders that it removes the need that the investors keep monitoring there stocks. But it has drawback that stop order may be executed even when there is short-term fluctuation.


Stop Limit Orders (STPLMT)
Stop limit orders are a combination of stop orders and limit orders. Like stop orders, they are only processed if the market reaches a specific price, but they are then processed as limit orders, so they will only get filled at the chosen price, or a better price if there is one available. For example, if the current price is 1.2567, a trader might place a buy stop limit order with a price of 1.2572. If the market trades at 1.2572 or above, the stop limit order will be processed as a limit order. If the market continues to trade at 1.2572, the limit order will get filled at 1.2572 or at a better price if there is one available. Stop limit orders may or may not get filled depending upon whether or not the market reaches the chosen price, and then depending upon how the market moves. Stop limit orders will trigger if the market trades at or past the stop price, so for a buy order, the stop price must be above the current price, and for a sell order, the stop price must be below the current price.

Market if Touched Orders (MIT)
Market if touched orders are identical to stop orders, except that they are used when the market price has already traded past the stop price, and the trader only wants the order to be processed if the market price comes back to the stop price. For example, if the market price is 1.3010, and the trader places a buy market if touched order with a price of 1.3001, the order will only be processed if the market trades at or below 1.3001. If the order is processed, it will be processed as a market order, and will get filled at the current best price. Market if touched orders will trigger the opposite way than a stop order, so for a buy order, the trigger price must be below the current price, and for a sell order, the trigger price must be above the current price.


Limit if Touched Orders (LIT)
Limit if touched orders are identical to stop limit orders, except that they are used when the market price has already traded past the stop price, and the trader only wants the order to be processed if the market price comes back to the stop price. For example, if the market price is 1.3010, and the trader places a buy market if touched order with a price of 1.3001, the order will only be processed if the market trades at or below 1.3001. If the order is processed, it will be processed as a limit order. If the market continues to trade at 1.3001, the limit order will get filled at 1.3001 or at a better price is there is one available. Limit if touched orders will trigger the opposite way than a stop limit order, so for a buy order, the trigger price must be below the current price, and for a sell order, the trigger price must be above the current price.
