Average true range. Average true range ( ATR) is a technical analysis volatility indicator originally developed by J. Welles Wilder, Jr. for commodities. [ 1][ 2] The indicator does not provide an indication of price trend, simply the degree of price volatility. [ 3] The average true range is an N-period smoothed moving average (SMMA) of the ...
Stop loss: Set a stop loss based on maximum loss acceptable. For example, if the recent, say 10-day, average true range is 0.5% of current market price, stop loss could be set at 4x0.5% = 2%. Conventional wisdom on stop losses set the risk per trade anywhere between 1%-5% of capital for a single trade; this risk varies from one trader to another.

Welles Wilder Jr., to find potential reversals in the market price direction of traded goods such as securities or currency exchanges such as forex. [ 1] It is a trend-following (lagging) indicator and may be ...
Kullback–Leibler divergence. In mathematical statistics, the Kullback–Leibler ( KL) divergence (also called relative entropy and I-divergence[ 1] ), denoted , is a type of statistical distance: a measure of how one probability distribution P is different from a second, reference probability distribution Q. [ 2][ 3] Mathematically, it is ...
f-number. Diagram of decreasing apertures, that is, increasing f-numbers, in one-stop increments; each aperture has half the light-gathering area of the previous one. An f-number is a measure of the light-gathering ability of an optical system such as a camera lens. It is calculated by dividing the system's focal length by the diameter of the ...
Soldiers affected by stop-loss were then serving, on average, an extra 6.6 months, and sergeants through sergeants first class made up 45% of these soldiers. From 2002 through April 2008, 58,300 soldiers were affected by stop-loss, or about 1% of active duty, Reserve, and National Guard troops. [12]
where = / is the average multiplicative gain at the reference distance from the transmitter. This gain depends on factors such as carrier frequency , antenna heights and antenna gain, for example due to directional antennas; and F g = 10 − X g / 10 {\textstyle F_{\text{g}}=10^{-X_{\text{g}}/10}} is a stochastic process that reflects flat fading .
