Trend Lines Cross 

This indicator will alert you on any cross of a Trendline. You can draw up to two trend lines and form a channel, a pennant , a triangle or a simple trend and when the price crosses either trend line the indicator  will provide you with alerts that you define plus an up or down arrow when the cross happened.

How to: 

Draw the 1st trendline and name it tl1. 

Draw the 2nd trendline and name it tl2.

Select which type of alerts you would like in the indicator properties and you are ready to go.

The indicator works even with a single trendline independent of the notification that there is one trendline missing.

Up and Down arrows will clear if you move either trendline.
