Pine 脚本/交易视图 - 计算每月交易日 (TDOM)

Question

I want to calculate the Trading Day of the Month in (TDOM) in TradingView/Pine Script.

I tried the following, but it didn't work:

int counter = 0

if (month != month[1])
    counter := 0

if (dayofmonth != dayofmonth[1])
    counter := counter + 1

plot(counter)

Any thoughts/help on how I can get TDOM?

You have to use the var keyword, or else your counter will be reset to 0 at every bar.

//@version=5
indicator("My Script")

var int counter = 0

if ta.change(month)
    counter := 0

if ta.change(dayofmonth)
    counter += 1

plot(counter)
