How to add indicator signals to the bottom of the chart?

[Emerson Gomes]

Hello everyone,

I am trying to figure out how to add indicator signals to the bottom of a chart, like it's done here:

Indicators in this example are MTF and only output red and green boxes.

Can this be done manually in the MQL5 UI or via code?

The function you're looking for is this:

#property indicator_separate_window

indicator buffers need to be created and given values accordingly

Thanks for your response. However, my question was more related to the format of the indicator output.

As you can see at the very bottom of the image above, the output of the last 2 indicators is simply a red/green box per bar according to the corresponding boolean value.

This kind of output doesn't match any of the DrawStyles in the docs (https://www.mql5.com/en/docs/constants/indicatorconstants/drawstyles)

I have seen this kind of plot in several EAs, however I have no idea how it is built. Maybe it's using some custom class?

They are of the DRAW_HISTOGRAM drawing style, but if you want other shapes, you could also use DRAW_ARROW.
