Trendline violation alert?

There are a few indicators out there that can tell you if a price is above or below a defined line, but what about a trendline? If I plot a line from X to Y, is there an indicator that can alert to tell me when the price goes above/below it?

Anyone have one or know where I can get one?

couldn't find one in my list of indicators. I have seen one that works with horizontal lines but not a standard trendline. You could write an indicator that places two trendlines on the screen (one for trendline breaks up and one for breaks down). You could then double click it and move it where ever you needed. it is easy within metatrader to detect what value the trendline is at a specific time so checking to see if the price had violated that trendline would be easy also. I wish I had the time to write it for you but I am booked up for a long time.

Go here, exactly what you want.
