15K is not a level we should be aiming right now, we have been going under 10k too many times in a row and I am afraid that it will happen again and when the next time it happens it may fall down way below 9 thousand as well and that is not something we can handle right now.
We should totally focus on moving beyond 10 thousand and staying there, we already moved beyond 10 thousand but we are still fragile, maybe going over 12 thousand and staying there for some weeks would be better, not the best but at least better. After that we can actually rally up to 14 thousand and if we can manage to stay around 14 thousand (a bit over or a bit lower doesn't matter) than we can try to go over 15, but until we fix this under 10 thousand all the time issue we can't even think about 15 thousand yet.
