The Weighted Close indicator is simply an average of
each day's price. It gets its name from the fact that extra weight is
given to the closing price. The Median Price and Typical Price are
similar indicators.
Interpretation
When plotting and back-testing moving averages,
indicators, trendlines, etc, some investors like the simplicity that a
line chart offers. However, line charts that only show the closing price
can be misleading since they ignore the high and low price. A Weighted
Close chart combines the simplicity of the line chart with the scope of
a bar chart, by plotting a single point for each day that includes the
high, low, and closing price.
Example
The following chart shows the Weighted Close plotted
on top of a normal high/low/close bar chart of Peoplesoft.
Calculation
The Weighted Close indicator is calculated by
multiplying the close by two, adding the high and the low to this
product, and dividing by four. The result is the average price with
extra weight given to the closing price.
