indicator moves within limits

[cesardefez]

Is there a manual to explain the configuration of this block?
I want to check the last n candles and let me know if the buffer of an indicator has been activated.
Could this block serve?

What do you exactly mean by 'activated'? Is it a specific value? A number?

[cesardefez]

I have an indicator that draws me arrows.
I want to know if in the last 5 candles, there is an arrow.
The arrow you draw does not have the object property, or at least it does not appear in the object box.
In other words, I want to know if in the last 5 candles the indicator has been visible.
Thank you

@cesardefez Does a buffer get a value if an arrow is drawn? In that case you may loop back and use indicator is visible block.
