EMV | R Documentation |
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.
EMV(HL, volume, n = 9, maType, vol.divisor = 10000, ...)
HL |
Object that is coercible to xts or matrix and contains High-Low prices. |
volume |
Vector or matrix of volume observations corresponding to the
|
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 |
The EMV is calculated by dividing the midpoint ([high + low]/2) move by the 'Box Ratio' (volume divided by the high minus low).
A object of the same class as HL
and volume
or a matrix
(if try.xts
fails) containing the columns:
The ease of movement values.
The smoothed (as specified by ma
) ease of movement values.
A buy/sell signal is generated when the EMV crosses above/below zero. When the EMV hovers around zero, there are small price movements and/or high volume, and the price is not moving easily.
