The chart is a 3 box reversal Point and Figure chart.
The chart is based on daily high and daily low prices.
The chart is a 2% logrithmic chart, ie each chart box represents
a price change of 2% of the value of the box above or below it.
Four possible support prices and six possible resistance prices
are shown, as well as the support/resistance lines.
A 'resistance' or 'support' point is a price where an issue's upward
or downward price movement may 'stall'. The ultimate result of the 'stall'
may be either a continuation or a reversal of price movement, depending
on whether there are more or less sellers than buyers at the specific price
point.

bullish trading channel.
