I don't know if someone has done this yet but the nickel squeeze that happened a few weeks ago could be comms.
Nickel = 5 cents
Nickel on periodic table = Ni -N = 14 -> i = 9 -> 15-9 = 5
5:5
I think this could be comms for "Hey look at this commodity squeeze." Almost every commodity that is important to tech is shorted to oblivion. So i think it is interesting that the one that could be comms is the one that blows up. I'd like some more eyes on this.
On another another note, Nickel had a massive run up back right before the 08 crash. Just another pattern to follow.
