Flat trend indicator

[Andreas Bauer]

Hello All,

as you know most indicators try to show us two ways, either trend is up > uptrend or trend is down > downtrend.

But there are also these indicators who try to show as a third way, the flat trend.

As attached below you see what I mean.

Thus this indi is a little old, I'd like to ask you whether you may have an indi which works as well and is new.

Of course best would be a mql file.
