How to read them

Ignore the noise and find the swing highs (the peaks) and swing lows (the dips), like Lesson 1. Ask: are the peaks getting higher or lower? Are the dips getting higher or lower? Both higher = uptrend. Both lower = downtrend. Mixed or flat = sideways.

Rule of thumb: you only need the last two or three swings. Most of the time, the 21 EMA’s slope agrees with the staircase.

Answers

Common mistake

Judging by the last few candles instead of the swings. COST’s bounce into October looks like an uptrend if you only look at the last week.

Try it

Pull up any stock you follow and mark its last three swing highs and lows. Which of these three charts does it look most like?
