Which trailing stop is correct?

[Campero]

HELLO. Which of these two trailing stops is the correct construction for a trailing stop?
Thank you for your help.

The second in the middle. The first and the third will give you many problems (they are the same).

You only need pink for each block, if you are working with data from a trade. Generally blue doesn't need pink
