WEIGHTED MOVING AVERAGE (WMA)
This TAI says that
some values are more important than others. This generally means
that the most recent values are weighted more heavily, but the term
WMA is also used to describe any weighting system. If no other details
are present, then here is an example of a 3-day weighted moving
average:
| Period |
Value |
WMA(3) |
Notes |
1 |
10 |

Because we don’t have three values to work with, the
first two WMA(3) are undefined.

2 |
12 |
|
3 |
14 |
12.67 |
(3 * 14 + 2 * 12 + 1 * 10) / 6 = 76 / 6 = 12.67
Why 6? 6 is the sum of the weights 3 + 2 + 1, necessary to
scale down the weighted-up values back to a single value |
|
4 |
16 |
14.67 |
(3 * 16 + 2 * 14 + 1 * 12 ) / 6 = 88 / 6 = 14.67 |
5 |
12 |
13.67 |
(3 * 12 + 2 * 16 + 1 * 14 ) / 6 = 82 / 6 = 13.67 |

Averages.

WEIGHTED MOVING AVERAGE — SIX PERIOD
A weighted moving average (see
WMA above) applies a weighting factor to each data value
based on how recent it is: the most recent value receives
the greatest weighting, while older values receive proportionally
less weight. For this technical analysis indicator (TAI)
the time interval to used is 6 days. More

WHITELIST
A whitelist is a list of pre-approved list of
senders from whom email will be accepted. You can whitelist
single email addresses (such as john@smith.com) or use wildcards
(such as *@smith.com) meaning you whitelist anything from
smith.com. If you are having problems receiving email from
us we ask that you whitelist *@positiveterritory.com
The details of how you create a whitelist depends on your
email program and your email provider. Please contact them
for assistance.

WHIPSAWS
The bane of technical
analysis, a whipsaw produces repeated, frequent, countermanding
signals from a technical analysis
indicator. Think “buy today, sell tomorrow, buy the next
day, sell the next day” etc. Generally, whipsaws result from
incredible market place volatility
or excessively sensitive parameters used in technical analysis indicators
(TAI).

WILLIAMS' %R (PERCENT R)
Abbreviated to W%R, sometimes just %R, Williams' &R
is similar to Lane’s Stochastics.
Williams’ %R is a momentum
indicator popular for measuring overbought
and oversold levels. More

WILLIAMS' ULTIMATE OSCILLATOR
Also known as Ultimate Oscillator, the Williams' Ultimate
Oscillator is a single bounded oscillator
created from a security's prices over three different time ranges.
The technical analysis indicator's (TAI's)values
range from 0 to 100 with 50 as the centerline. Prices below 30 indicate
the security is oversold,
while prices between 70 and 100 indicate the security is overbought.

X
x+ (cross over)
This is a shorthand notation we use to indicate cross
over. For example A x+ B means A crossed over B. A can be a technical
analysis indicator (TAI) such as a simple
moving average or a value. B can be another TAI or a value.
For example: SMA(50)(Closing Price) x+ SMA(200)(Closing Price)
means that the 50-day simple moving average of closing price crossed
over the 200-day simple moving average of closing price.
Another example: Volume(Today) x+ SMA(20)(Volume) which means today’s
volume crossed over the 20-day simple moving average of volume.
Still another example: ADX(Today) x+ 30% This means that the ADX
crossed over the 30% value. Why is that important? See the section
on ADX – The Average Directional
Movement Index.

x- (cross under)
This is a shorthand notation we use to indicate cross
under. For example A x- B means A crossed under B. A can be a technical
analysis indicator (TAI) such as a simple
moving average or a value. B can be another TAI or a value.
For example: SMA(50)(Closing Price) x- SMA(200)(Closing Price)
means that the 50-day simple moving average of closing price crossed
under the 200-day simple moving average of closing price.
Another example: Volume(Today) x- SMA(20)(Volume) which means today’s
volume crossed under the 20-day simple moving average of volume.
One more example: ADX(Today) x- 20% This means that the ADX
crossed under the 20% value. For why that might be important see
the section on ADX – The Average
Directional Movement Index.
See also x+ above.
