This helped me these days when bitcoin was going up because I set it to get information. Once the price reached the alerting point I would just got alert and check trading view to see if it is correct and when I would checked all would be accurate. And that is why I also recommended to you after the first time I used it to get the alert.
So how does it actually help you, then? You're informed that the price has reached a certain point, you proceed to TradingView to confirm it, and yes it's correct, and then? You get back to whatever you're doing?
I don't know with others here but I've long stopped alerting myself of the prices. I used to when I tried trading. I stopped years ago with a little disappointment, and so now I already find price alerts of little use. I've now been hodling and I don't care much if I'm not informed of the price for weeks.
I guess the title says it all, It's just a notification, just to notify us and keep us informed and that's it. It's purpose is to keep us updated all the time.
We're quite like the same, I am also a hodler so I'm aiming for long term so price notification is just not too useful for me, it will just annoy me but for some traders maybe it is very useful and convenient for them.
