Need help gettting simple alert signal to work

[rgh1rgh]

I was trying to create a simple alarm alert when the bar changed direction so I would not have to watch the computer screen all of the time. I used the formula wizard. It works fine for both point break and candlesticks. What I really wanted it for was Renko. When you first apply the formula it produces the right signals. But as real time goes on it puts them on the chart at random. Anyone know how I can fix this?

Thanks
Randy
