Of course it is very influential, if there is a dump then you will be safe, for example if you put your stop loss at -5%,
and when it happens dump it is at -20%, then your money will be safe from another -15% loss, of course it can.
give you a new asset again when you buy back later, even though the stop loss looks useless, for me stop loss is very important at a certain time
Stop loss is never useless, there is a reason why there is stop loss and it describes itself already.
Some people and their greediness, that’s what makes them feel like stop loss is useless.
Just because you used stop loss for once and then you ended up missing a little opportunity doesn’t mean it is useless.
There are times like you have said, when the loss will be too much, but those who are making use of the stop loss feature will have their ass saved from too many losses, but those who don’t have it on will lose way more. That’s just how it is, there will always be both sides, and you just have to know how to use it properly.
