Unsolved The difference between "For each Trade" and "If trade"

[AlirezaTrade]

Hello,
What is the difference between these two blocks?
When should each be used?
Which block is faster to process?
For the picture below, I want to use one of these two blocks, I don't know which one is better.

Dark pink goes above light, the pink blocks are 2 sections of the same code. For each looks at trade details, if trade just checks if there is a trade running.

@jstap Thank you so much. Now, which one should I use for the above photo, which is for trailing stop?
