The drawdown is the measure of the decline from a historical peak in some variable (typically the cumulative profit or total open equity of a financial trading strategy). [ 1 ]
It is the height of the free surface of water above a given point beneath the surface. [4] Pumping level is the level of water in the well during pumping. [8] Specific capacity is the well yield per unit of drawdown. [8] Static level is the level of water in the well when no water is being removed from the well by pumping. [8]
Drawdown (economics), decline in the value of an investment, below its all-time high; Drawdown (hydrology), a lowering of a reservoir or a change in hydraulic head in an aquifer, typically due to pumping a well; Drawdown card, used for testing paints and coatings through wet film preparation; Drawdown chart, paper used to test various coating ...
Calmar ratio (or Drawdown ratio) is a performance measurement used to evaluate Commodity Trading Advisors and hedge funds. It was created by Terry W. Young and first published in 1991 in the trade journal Futures .
In hydrology, a well test is conducted to evaluate the amount of water that can be pumped from a particular water well.More specifically, a well test will allow prediction of the maximum rate at which water can be pumped from a well, and the distance that the water level in the well will fall for a given pumping rate and duration of pumping.
A loss of just over 24 percent on May 5, 1893, from 39.90 to 30.02 signaled the apex of the stock effects of the Panic of 1893; the 2007–2008 crash was a 61.8 percent retracement thereof that began on October 11, 2007, and lasted until the closing low on March 9, 2009.
Climate drawdown refers to the future point in time when levels of greenhouse gas concentrations in the atmosphere stop climbing and start to steadily decline. [1] Drawdown is a milestone in reversing climate change and eventually reducing global average temperatures. [ 2 ]
Drawdown charts are rectangular pieces of non-fluorescent paper [1] which are used to test a variety of coating properties. These properties include opacity , spreading rate , penetration, and flow & leveling behavior. [ 2 ]
