How does the release of an economic indicator cause price movement?
To answer this question, let's take as an example the major employment data outside the agricultural sector in the US – Nonfarm Payrolls. This is a monthly report that reflects changes in the number of urban jobs over the past month. Relatively high values are considered positive for the US dollar (USD), causing a growth rate (the more jobs, the more money from the population, the higher purchasing power, the stronger economy, the more attractive for investments).
And vise versa: the data below the forecast usually provoke a decrease in USD.
