This indicator will draw a line on your chart to show the Nonfarm announcement date and a line showing the Nonfarm announcement time for that day.
Because normally the Nonfarm announcement date is not simply the first Friday of the month. Because there are days Nonfarm days can be 8 or 9 or 10.
By checking the entire history of nonfarm announcements, I found some more rules such as if the first Friday of the month hits a holiday, the nonfarm day will be the friday of the following week. The previous months are 28, 29, or 30 days and if the first Friday of this month is on the 3, 2 or 1, the nonfarm day will be the friday of the following week.
Since this type of indicator is not available on the Tradingview library, I have put it up for everyone's convenience to backtest the price movement on nonfarm days to better support trading or simply to avoid trading at time of announed nonfarm.
