Well, the fast dumps on the 60-minute chart mean the trends are quicker. If this is a "C" down from yesterday's highs, we would either have an 87, 54, or 43 point drop from yesterday's highs. I'm not even sure we'll get the 43-point drop.
The drop from 1684 to 1597 would be the A Down, the rise from there to 1661 would be the B up, with a C down in progress.
The action this afternoon looked like the B up off the C down, which would leave a dump. Alternatively, we could just meander out until we get past a falling resistance line and then ramp.
