Typical Price

[eSignal]

File Name: TypicalPrice.efs

Description:
Typical Price

Formula Parameters:
Typical Price: Blue
AVG: Red
Length: 9
Typical Price Thickness: 1
AVG Thickness: 1
Display Title Value: False


Notes:
The Typical Price for each bar is calculated as an average of 3 values:
high, low and close. This value is then plotted on the chart. An average
of the Typical Price from the most recent number of bars specified by the
input Length is also plotted. Using the Typical Price instead of the close
in calculating and plotting, say, a moving average weighs the high and low
into the calculation.
This indicator can be used in a manner similar to the Mov Avg 2 Lines,
with attention given to the direction and relative position of prices,
Typical Price and the average of the Typical Price. (Typical Price is
known to some traders as the pivot point.)
