VELOCITY AND ACCELERATION
The velocity
is
a measure of how quickly the market moves from one point
to another. The
formula for velocity is:
Velocity =
d/t
where d =
distance moved
t
=
time of move
In trading, the
distance is measured by price, so a market that moved from 100 to 105 in
one day would have a velocity of:
Velocity = 5/1
=
5 points/day
Velocity is similar to the
momentum calculation. The acceleration
is a measure of how quickly the velocity changes.
The formula for
acceleration is:
Acceleration = v/t
where v =
change in velocity
=
time
In the previous example,
the market moved from 105 to 113 the next day, so the
acceleration is:
VeiocitY2 = (113 - 105)/1
= 8
The
change in velocity = V2 - VI =
8
- 5
=
3
The
acceleration =
3/1
= 3
The velocity,
acceleration, and volatility calculations are ways of
measuring market movement. The velocity and acceleration
measurements provide an indication of how fast the
market moves. The volatility calculation shows the
likelihood of market movement within a certain time or
provides a measure of price movement in the past.
In calculus, velocity is
the first derivative of distance, or the slope of the
line, and acceleration is the second derivative of
distance. A derivative is the change of one variable
with respect to another variable, so velocity is a
measure of the change in distance with respect to time.
Acceleration is the change in velocity with respect to
time.
