When you are a long term, you don't need any. I don't have "losses", I have "need to wait a bit more I guess" periods, that's it. Have I never sold when I am at a loss? Of course I have, and that's fine, you could always have those days. However, I usually don't sell and just wait, so it makes a lot more sense instead. This allows me to just wait and wait, and eventually, I end up with the price going back up, and me in profit yet again. This should be the situation as far as I can see, and from what people are talking about, long term has been great for many of them as well. Just do that, and you should be fine.
