Issues while converting series to const string for plotshape text

Question

I have been trying to print the current volume as a plotshape text label using the following code...

plotshape(EntryCondition, style=shape.labelup, title="Buy flag", location=location.belowbar, color=color.lime, text=str.tostring(volume)) 

but I keep getting this error..

Cannot call 'plotshape' with argument 'text'='call 'str.tostring' (series string)'. An argument of 'series string' type was used but a 'const string' is expected

Any advice on how to fix this?

Answer 1

There is no way to force the plotshape() to accept series string, unfortunately. Use the label.new() function instead, which allows to plot and change the text dynamically.

if longCondition
    label.new(bar_index, low, str.tostring(volume), color = color.lime, style = label.style_label_up)
