Ask Line +20

[Adeodatus]

Maybe a hand with this too? this part won't clear out all the red highlighted script:

for i = 0 to 19
{
plot extendedLine = if barNumber() == i then HorizontalLine else extendedLine[1];

and the last ( } )also red highlight.


Will it show a line at ask and run out to the right 20 ?



plot HorizontalLine = if barNumber() == 0 then ask else HorizontalLine[1];
HorizontalLine.SetDefaultColor(color.red);
HorizontalLine.SetLineWeight(3);
HorizontalLine.AssignValueColor(if HorizontalLine >= close then color.red else color.green);

# extend line for 20 periods
for i = 0 to 19
{
plot extendedLine = if barNumber() == i then HorizontalLine else extendedLine[1];
extendedLine.SetDefaultColor(color.red);
extendedLine.SetLineWeight(1);
extendedLine.SetStyle(curve.SHORT_DASH);
}

thinkscript has a function called fold, for creating loops
https://tlc.thinkorswim.com/center/reference/thinkScript/Reserved-Words/fold

but, fold can't include any output commands. all it can do is calculate a number. you can't put a plot within a fold loop. a separate plot command is needed for every desired plotted object.

...extend line for 20 periods
for i = 0 to 19...

can't control other bars , can only draw on the current bar and change values on current bar.
so a loop can't change data on other bars.

could save the barnumber on the bar that is first plotted and add 20, and save that value. then compare each barnumber to those, to see if the current bar is between them. if so plot a line.

but, if another signal occurs during the 20 bars, the line would start over, and plot for 20 bars...
if you want multiple lines plitted on 1 bar, need to have multiple plot formulas.


i don't try to fix partial codes. if you have this much wrong in this short sample, probably most of the code is wrong.
Not all errors will be highlighted red at first. as you fix one error, more may show up, and so on.

post the whole code and someone might try to fix it.
