Soon it might be a good time to buy TLT or TMF. The top for bond yields looks near to me as it gets close to this channel top. A good confirmation for a pullback would be to watch for a break in the stoch support.
You could argue that it is also making a megaphone pattern with the support at 2.6% and the resistance at the channel top. I looked into this pattern and it could be bullish or bearish unfortunately, so it is hard to say what it'll do until it breaks either side. I charted a bullish possibility and target if it does break out, such a move could end up quite bad for the market, so I hope it won't happen.
