Don't do much technical stuff, but doesn't OBV use closing prices and volume? If that's the case...isn't OBV pretty much useless because we constantly see someone ticking it down in the last seconds and making it a "down day" instead of an "up/neutral day"? And the volume seems mediocre at best so does it really even matter? Realistically technicals don't matter even outside of this since this is purely going to be driven by news and not technicals anyway, no?
