Can I get a value from alert or drawing?

[Matz371]

Hello! May I ask a question that, how can I get a value from an alert or a drawing such as a price level, and it into a script? Thank you!

I would like to use the value as a reference number in other studies.

Otherwise, can I input or refer to a different value for a different individual stock?

Thank you very much for your help!

The TOS platform does not have the ability to interact w/ lines and other graphics created w/ the drawing tools.
This means that you can not "get a value from an alert or a drawing such as a price level into a script"

@Matz371, you did a great job posting your question. It was clear and had easy to understand pictures to go along with it. Some questions on the forum are extremely difficult, if not impossible to understand.

Regarding @MerryDay's comment, even in other platforms like NinjaTrader it's extremely difficult to get these kinds of values. You have to loop through all of them (using the C# language) and then determine what to do with it. It's no surprise ThinkScript (a scripting language, not a programming language) doesn't have this ability. That said, don't feel too bad about it given how complex this is even in much more complex applications like NinjaTrader.

are you wanting to draw horizontal lines at some price level?

you can have a study ask for number(s).
you can have a study ask for number(s) that are associated with a specific symbol. then when that symbol is viewed on the chart, those line(s) will be drawn.

go to the edit studies and change the parameters of this study to 3 stocks that you look at and enter 2 prices for each stock.
it will draw 2 lines on 3 different charts.

def na = double.NaN;

input symbol1 = "SPY";
input sym1_level1 = 0;
input sym1_level2 = 0;
input symbol2 = "SPY";
input sym2_level1 = 0;
input sym2_level2 = 0;
input symbol3 = "SPY";
input sym3_level1 = 0;
input sym3_level2 = 0;

plot z1;
plot z2;
if (GetSymbol() == symbol1) then { 
z1 = sym1_level1;
z2 = sym1_level2;
 } else if (GetSymbol() == symbol2) then { 
z1 = sym2_level1;
z2 = sym2_level2;
 } else if (GetSymbol() == symbol3) then { 
z1 = sym3_level1;
z2 = sym3_level2;
} else {
z1 = na;
z2 = na;
}
