MT4 Trendline alerts - Is it possible?

Hey,

So I know that I can set an alert at any price point I want. And that is built into standard MT4.

But is there a way I can draw a line on the charts that is not horizontal, i.e it would cross multiple price levels, and have an alert go off when it hits that line?

So for example the trend is down, I want to get an alert when price retraces back up to the trend line. So I draw on my trend line and set the alert.

I don't know what price it will be when it hits the trend line, so I cant set a normal alarm. But I do want notice when the trend line is hit again.

Any ideas? Or EAs?

I would think that there are already a number of EAs that do this out there already.
As a newbie coder it sounds like an interesting project as I haven't done much work with graphical objects.
I'm a bit busy with other things at the moment, but if you have no luck give this topic a bump in a couple of weeks and I will see if I can sort it.

I attached on indicator which is doing what you need.

How did I find it ?

There is a Search function in this forum.
I typed "Trendline alert" into the search field and got 11.700 hits.
Just a hint for you and other traders who search for something.
Most things already exist.
