I was a market maker on the New York options floor. They had a system you could employ on a chart page. They had a horizontal curser you move up and down to set an alert at any price you wanted. It would flash on the screen or a bell would go off letting you know the stock traded through the price you set. This was one of the best tools that everyone took advantage of. I have never seen it on any other program. I am sure it is simple to put in your program. George
