Mometer
Because trends are composed
of a series of price pullbacks and
retracements, momentum plays
a key role is assessing trend strength
and potential weakness. As such, it is important to know when a
trend is likely to be becoming exhausted. Strong momentum does not
always lead to exhaustion and a reversal,
but it does signal that something will most likely be changing
soon, and that the trend may consolidate or retrace. After all,
trends must stop at some point and retrace or pullback. All trends
do it, and they always will.
Price momentum refers to the direction and
magnitude of price movement. Measuring momentum gives traders
insight on where and when price is most likely to slow or stop and
pullback. The Mometer will help you to evaluate price momentum and
show you what exhaustion is likely to do to the near term
direction of a trend.
Defining Price Momentum
The magnitude of price momentum is measured by
the length of short-term price moves. The beginning and end of each
move is established by price pivots or anchor points. Strong
momentum is exhibited by a steep slope and a long price move. Weak
momentum is seen with a shallow slope and short price swing (Figure
1).

For example, the length of the up moves in an
uptrend can be measured. Longer up moves suggest that the uptrend
is showing increased momentum, or getting stronger. Shorter up
moves signify weak momentum or price drift. Equal length up moves
means the momentum is consistent, but not strong nor weak.
For our purposes, we are
simply looking for an indication that price is showing strong
momentum according to an underlying set of data. It is not
important to watch this data in order to determine if this
condition does or does not exist. We simply need to keep our eyes
on our charts and only the necessary information will be used to
alert us to the fact that the condition exists. Therefore the need
for multiple charts, monitors, computers, and indicators is greatly
diminished.

Description
The Mometer indicator allows
for the user to define threshold levels for acceptable momentum
signals. The indicator reads the bar sizes (Hi to low, in
ticks/pips) of each of the bars in the
number of bars in the lookback period and averages them. The
current bar is then compared to this average and if it exceeds this
average by a user definable percentage, this bar becomes a
potential anchor bar to begin a series of bars that could indicate
increasing momentum. Each subsequent bar is then measured relative
to the previous bar to determine if that bar is showing steady or
increasing momentum.
There are times in a momentum
series when a small body bar in the opposite direction of the
momentum is displayed. If the user would like to filter these small
bodied bars, a parameter setting is available for the size body to
filter by percentage of the previous bar size. This will remove the
bar from consideration in the momentum series and the series will
continue until a larger bar in the opposite direction that exceeds
the filter is displayed. This opposite direction bar will signal
the end of the current momentum series. However, depending on the
parameter settings, this bar could also be the beginning of a new
momentum series in the opposite direction.
The first bar of a momentum
series will not necessarily be the first bar in that direction of
the series. In fact, it is common for momentum to increase more
slowly and build. Momentum may only be evident after several bars
in a particular direction. When this is the case, the Mometer
indicator will back paint all of the bars that preceded the anchor
bar but were in the proper direction. This is done simply to help
the user identify that these slow momentum bars where part of the
series even though it was not evident until later. This gives the
user a better sense of the actual momentum and better information
for making quick decisions.

00. Lookback:
The number of previous bars to combine and
average to determine if the current bar qualifies as an anchor bar
for a momentum series.
01. Threshold 1:
The current bar must be this % or more of the
size of the average of the lookback bars to generate an anchor
bar.
02. – 04.: Threshold
2-4: The current bar must be this % or more of the size of the
previous bar to generate a signal.
05: Filter Opposing Direction
Threshold: If the current bar closes in
the opposite direction of the bars in the momentum series, it must
be this % or less of the size of the previous bar to keep from
canceling the momentum series.
06. Anchor Bar Spread
Minimum: Minimum number of tick size to
qualify as an anchor bar to start a series of momentum.
07. Clear Historical
Sequences: Leave all historical
momentum series on the chart or only the current series is
displayed.
Using the colors selected for
Thresholds 00 - 04 (Figure 3 at left) the user would expect to see
black bars at the beginning of a momentum series. As the momentum
increases throughout the series, the bars would become lighter
shades of gray. The lighter the shade of gray, the more likely
momentum is going to start showing signs of exhaustion and thus a
retracement or pullback is more likely. (see Figure 1)
