米国株の執行方法を忘れやすいので日本語で整理
A market order is an order to buy or sell a security immediately. This type of order guarantees that the order will be executed, but does not guarantee the execution price. A market order generally will execute at or near the current bid (for a sell order) or ask (for a buy order) price. However, it is important for investors to remember that the last-traded price is not necessarily the price at which a market order will be executed.
成行: Market Orderは売買を直ちに行う発注方法です。この場合、必ず執行はしますが、執行価格が何になるかは分かりません。
A limit order is an order to buy or sell a security at a specific price or better. A buy limit order can only be executed at the limit price or lower, and a sell limit order can only be executed at the limit price or higher. Example: An investor wants to purchase shares of ABC stock for no more than $10. The investor could submit a limit order for this amount and this order will only execute if the price of ABC stock is $10 or lower.
指値: Limit Orderとは、特定の執行価格またはそれよりも良い執行価格で約定させる発注方法です。例えば買いの場合、Limit Priceかそれより低い価格で約定が行われます。
A stop order, also referred to as a stop-loss order is an order to buy or sell a stock once the price of the stock reaches the specified price, known as the stop price. When the stop price is reached, a stop order becomes a market order.
逆指値: ストップロスとも呼ぶ。指値注文が現在よりも有利なレートを指定するのに対し、逆指値は、現在のレートよりも不利なレートを指定して発注する注文方法です。市場価格に抵触した瞬間にMarket Order(成行)で発注が行われます。
A buy stop order is entered at a stop price above the current market price. Investors generally use a buy stop order to limit a loss or protect a profit on a stock that they have sold short. A sell stop order is entered at a stop price below the current market price. Investors generally use a sell stop order to limit a loss or protect a profit on a stock they own.
投資家は一般的に、リスクを限定する目的で逆指値を置きます。
