Is it possible to do this?

[Jowin6789]

Hey all,

Been looking at using a MA or support resistance indicator to using in my EA but none are as good as me drawing in key support resistance lines.

So, is it possible to get an EA to recognize horizontal lines you have manually drawn onto the chart, and what would they be named as standard, and would they all be named the same or would MT4 name them HLine1, HLine2, HLinen for example?

Thanks for any help!!

1. Add lines to chart

2. Right-click

3. Object List

4. You will see the lines you drew with the names given to them.

Can an EA detect these? Probably. I haven't tried it myself, but this thread looks applicable.

It can be done as with any object - as long as you know the exact name of the object you are looking for

[Jean Francois Le Bas]

you can filter any object by name, type, color, date of creation, you name it, this is powerful !

Here's an example of how you could add HLines dropped on the chart as S/R in your EA
