DEFINITION of 'Downtrend'. Describes the price movement of a financial asset when the overall direction is downward. A formal downtrend occurs when each successive peak and trough is lower than the ones found earlier in the trend. Notice how each successive peak and trough is lower than the previous one. For example, the low at Point 3 is lower than the low at Point 1.
A dioptre (uk), or diopter (us), is a unit of measurement of the optical power of a lens or curved mirror, which is equal to the reciprocal of the focal length measured in metres (that is, 1/metres). It is thus a unit of reciprocal length. For example, a 3-dioptre lens brings parallel rays of light to focus at 1â3 metre. The same unit is also sometimes used for other reciprocals of distance, particularly radii of curvature and the vergence of optical beams.
