For each, you can set display or hide. 　　1) Zigzag line　　　　　　　Connect highs and lows alternately with zigzag lines. 　　2) Envelopes　　　　　　　　 Connect highs with highs and lows with lows with lines. 　　3) Marks for extreme values Display marks at highs and lows. 　　4) Marks for extreme value history Display marks on the history of highs and lows. You can choose either “Wicks (Highs/Lows)” or “Bodies (Open/Close)” as the target for extracting extremes. This is an example run with the default settings. By default, all of 1–4 are displayed.
