Tip (s):

R₃ and S₃ are good indication for the maximum range for extremely volatile days but can exceeded occasionally.

Pivot lines work well in sideways markets as prices will most likely range between the R₁ and S₁ line.

In a strong trend, price will be low through a pivot point line and keep going.

If there is significant news to influence the market price may go straight through R₁ or S₁ and reach even R₂ & R₃ or S₂ & S₃.
