How Can I: alert when price cross a drawn trendline?

 
Hello

Is it possible to create an alert to jump out when a price cross a previously drawn trend line?

What I mean is: I have a pattern and appropriate trendline already existing on the chart. I'd like to be alerted when this trendline is broken. Is it possible? How or any hints about?

If I get subsequent high/lows to draw a line it won't be streight, but rather zig-zag. I want 1st to drow the streight line and then ti lock for a break. I hope I've explained clear the idea . . .

Thank you

Ivo
 
Ivo,

I have an expert which does essentially this. To be able to query the trendline though, I've had to ensure each different trendline has a specific label.

price_top=NormalizeDouble(ObjectGetValueByShift("TrendlineTop", 1),MarketInfo(Symbol(),MODE_DIGITS))

The trendline in this case has the name "TrendlineTop"

Hope this helps you out - certainly works for me.

Cheers
Martin
