Since Sept 2010, every time the TDC chart gave a buy signal the rally lasted approx one week before topping. Then we pulled back. Only once did it run longer and that was on Sept 23 and the run was until Nov 11. Most times the stock fell back to the starting point. The present buy signal was Mar 15 and the low of the day was $0.135.
I do not trade TDC but I thought that I would point that out for those who want to skim a few points every cycle. By March 23 we may see the next dip down.
Hope I am wrong and that this is a longer run with new highs.
Cheers!
