Divergence Rule 2

Hi all,

I’m new to Forex and have been religiously going through the lessons at the school. I’ve come across 1 part which I’m hoping someone can help me out with.

Under the lessons on divergences and trading divergences, the school provided 9 rules to follow. Rule 2 mentioned to draw lines on successive tops and bottoms? I’m not sure what they mean here and there was no chart for illustration. Does it mean to backtrack and draw the lines in order to see if we are really looking at lower highs / higher lows?

Thank you!
