How to convert a V4 study code to V5 to add it to an indicator?
I have an indicator I built running on V5 pinescript and I want to add this one which is written in V4 pinescript:
//@version=4

Would it be possible to convert it? I tried to delete the study line, but it gave me this error:
line 266: The arguments 'maxval', 'minval', and 'step' cannot be used with the input() function. You can use the input.int() or input.float() functions to specify a range of input data values.
Solution
You can use the auto converter tool from the menu (three dots right next to the "Publish script" button.
