Every day is a new day. I don't think historical charts are meaningful at all. People tend to get so detailed in them to try to figure out what's going to happen. Supply/demand, public reaction, economic news, etc are what drive prices of silver/gold up and down. Not fancy lines on yesterdays chart.
It generally indicates a major price move, it also uses or is a function of the 20-day MA and the 'tighter' the bands the more significant t the move. I'd say it would probably shoot up based on the charts alone; but there's apparently more going on with this thing according to other posts.
I'll commit here and say $32 or more the longer the squeeze continues. I'm not a guru BTW.
