Hate to break it to you, but the trading range has been between $1.27 and $1.45 for over 1 month, and before that it was between $1.66 and $1.82 for about 2 months, and before that between $3.00 and $3.22 for about 1 month, and before that $3.28 and $4.04 for about 3 months, and so on.
In fact, there has been a steady decline over the past 3 years since its peak at $23.75. Now we are at $1.30 and according to the firmly established trend, TSTC is going to be at a much lower trading range by the end of the year, IMHO.
