I might be blind but...

There is no horizontal line option for variable output using Object on the chart.
trendline check
vertical line check
horizontal?
Discrimination of some sorts?

@william29 Which block are you talking about exactly?

[William29]

Modify Variables one. You'd sellect object in the chart and the property tab does not have a horizontal line

@william29 Hi @william29! As @l-andorrà says, if you do not explain yourself better it is impossible to understand what you are saying, first hang up the project link and indicate which block you are referring to otherwise it is impossible to help you since I think I understand your idea (I have a panel that makes use of horizontal and vertical lines and I have no problem) otherwise it is how they say in Spain "Give blind sticks".

@william29 Sorry, I missed your reply. You can do it this way:

Just type the name of the horizontal line and you will get its price level.
