It is expected that Alert feature should be able to: 1) Set the alert notification limit For example : price move above certain price level. Sometimes the price move up and down (e.g. Choppy environment) and thus may trigger a lot of alert notification. Can the user set a limit ? e.g. within a period (e.g. day or week), the alert notification only notify user limited times but not every time 2) Allow the alert write once and then re-use. For example: a user create an earnings alert (notify the user when earnings call happen in coming 14 days) for stock A, the user can then apply this alert to the list of stocks / stocks in the watchlist in one go (i.e. do not require to re-create and apply alert to individual stock one by one)
