Key takeaways from Point and Figure charts

Here are some key takeaways from this module so far.

Point and Figure charts show the demand and supply: demand pushes up a column of Xs, supply pushes down a column of 0s.
When demand overcomes supply, and an X breaks above the previous column of Xs, a basic Point and Figure buy signal is generated. When supply overcomes demand, and a 0 breaks below the previous column of 0s, a basic Point and Figure sell signal is generated.
All Point and Figure patterns and signals are based on these basic patterns in various combinations.
The wider the pattern, or the more times a level is challenged, the stronger the buy or sell signal from the pattern.
Point and Figure patterns can be continuation, as well as reversal, patterns.
The ability to breakout, be forced back and then breakout again is a strong sign.

Patterns vary according to the reversal size used.

More rigid and recognisable formations than those in 1 -box charts.
Easier to categorise and name.
All decompose into either of the 1 -box chart patterns.
Not every buy and sell signal should be taken, as it could be part of a larger, more complex pattern.
Always look left to see additional support or resistance.
Sloping bottoms make patterns more bullish, sloping tops make patterns more bearish, whereas sloping tops and bottoms indicate uncertainty.
Sideways movement or congestion is an important part of Point and Figure analysis and indicates accumulation at bottoms and distribution at tops.
Analysis of congestion helps to predict the likely breakout direction.
Trend lines are vital to Point and Figure analysis and no Point and Figure chart should be drawn without them.
Trend lines at 45° provide an objective way of establishing trends in 3-box charts.
Taking note of the trend enhances standard Point and Figure signals.
