Great British pound divergence

There is something going on with the currencies. The UK left the EU. Something has to give. The on balance volume is bouncing off a very low level but is it now in an uptrend? The red bars in the volume keep getting bigger. While the green bars are fairly flat. I think a decision is coming at the apex of the triangle. I think go short the British pound. If it can't get over the levels set by the OBV. Negative 20.82 million seems to be a key level. There's not much support underneath price. Until we see a higher high and a higher low it doesn't look good.
