Falling wedge pattern on 30 year bond

There's something going on here. RSI looks like it is heading up to test the upper high horizontal resistance. OBV has a weird increase in June to a higher level at the same time as there is a massive spike in volume. But price keeps going down in a falling wedge which is bullish. I say go long the 30 year if and when it breaks out of the wedge to the upside. It might fake out down or retest from a breakout.
