The Typical Price
indicator is an average of the day's price, and is therefore similar
to the Median Price and the Weighted Close. Used to give a single-line
plot of the day's average price, the Typical Price is calculated
by adding the high, low, and closing prices together, and then dividing
by three. For day trading, the Typical Price may help you to get
a clearer view of what the main thrust of the day's action was.
