What is aon in trading

AON orders that cannot be executed at the time of submission remain active during trading hours until they are filled or canceled. This prevents partial fills, which is particularly useful when transacting with thinly traded securities. One major drawback is that, since these orders have specifications, they can take longer to execute than normal orders. Larger AON orders or those in illiquid markets, however, are often more difficult to fill because the order composes a greater percentage of the number of shares traded daily.

The investor has specified both the number of shares and the price required to fill the order. Many portfolio managers use technical analysis, defined as the scrutiny of stock price patterns and trading volume, which may necessitate using an AON order to enter or exit the market. When a stock price trades above or below a range of trading, the price may indicate a future trend. Technical analysts call this trading pattern a breakout , meaning the share price continues to climb.

Portfolio managers also use fundamental analysis , which can be defined as a study of a company's financial statements and financial ratios. Managers compare the financials of a company to a similar business in the same industry, which can often aid their decision to either buy or sell that company's stock. As they do with technical analysis, portfolio managers use AON orders to buy and sell stocks based on fundamental analysis.
