Arms' Ease of Movement Value (EMV) emphasizes days where the security moves
easily and minimizes days where the security does not move easily. Developed
by Richard W. Arms, Jr.
Usage
EMV(HL, volume, n = 9, maType, vol.divisor = 10000, ...)
Arguments
HL
Object that is coercible to xts or matrix and contains High-Low
prices.
volume
Vector or matrix of volume observations corresponding to the
HL object.
n
Number of periods for moving average.
maType
A function or a string naming the function to be called.
vol.divisor
An increment to make the results larger and easier to work
with.
...
Other arguments to be passed to the maType function.
Value
A object of the same class as HL and volume or a matrix
(if try.xts fails) containing the columns:
[object Object],[object Object]
Details
The EMV is calculated by dividing the midpoint ([high + low]/2) move by the
'Box Ratio' (volume divided by the high minus low).
