The printing of paper money was also associated with wars, and financing of wars, and therefore regarded as part of maintaining a standing army.
Trend is a term used to describe the persistence of price movement in one direction over time. Trends move in three directions: up, down and sideways. Trend indicators smooth variable price data to create a composite of market direction. Generally, the trend could be either UP, or DOWN, or TREAD (flat).
