NFP (non farm payrolls), describes the employment rate in the non-farm sector for a month in the United States. NFP is used as an indicator as well as the moment that forex traders have been waiting for. So the NFP will be published by the Bureau of Labor Statistics, on the first Friday of each month containing data for the previous month. I will try to explain in simpler language if you read high NFP data, the USD exchange rate will be stronger and vice versa. Or if the number of workers increases, there will be less unemployment so that per capita income will be higher and of course consumer spending will increase and vice versa if income is low, people's purchasing power will be smaller and will affect the direction of USD movement.
If you are going to use NFP data then you need to monitor major currency pairs, such as GBP/USD, USD/JPY and EUR/USD,
Usually the period of highest volatility is the first 30 minutes after NFP data is published but it is likely to last up to 2 hours. There are two other indicators you need to pay attention to such as the unemployment rate and average hourly earnings.
