I have some 100 shares of a reputed company since 3 months. The share price is fluctuating every day. sometime price go low in the morning and high in the afternoon again low or high and so on. If I sell the shares when it reach high in any point of the day, will i get the share value at that time I sold i.e. at peak or it is the value of the share at the end of the day value.
For shares in a company, the order executes at whatever market price is in effect at the moment the shares are sold. This is called a Market Order. You can also set your own price (a Limit Order) and the shares will sell when and if a buyer can be found at that price.
For mutual funds, the order is executed at the next closing price. So on a trading day, the shares are sold at that day's closing price.
