Price Alert Creator

The main function of the indicator is to listen to a certain key shortcut "a":

The indicator then sends "notification" alerts to the server for all horizontal lines that are drawn on the current chart (which have been drawn using the built in drawing tool). It uses the built in terminal alerts (which are shown if the chart property "show trade levels" is actived), so that even when switching the chart symbol, or using another client, the alerts should still work. All horizontal lines are deleted from the chart as soon as the alerts have been sent out to the server.

All alerts for the symbol of the current chart can be removed from the server by pressing the shortcut key "d".

I need the source code, too. It should be included in the price.
