Watch the bright green line...

I've drawn a bright green horizontal line on the OBV indicator. Notice how the OBV has been on a downward trend since 11k. Now it's beginning to flatten out, a sure sign that the downturn is ending.

When the price hit 6k, the OBV curved sharply down to a point and then curved upward sharply toward 11k. Clearly these sharp movements in OBV are unsustainable. The OBV then begin to flatten and then a downturn ensued for several months. This time the OBV is slowly but surely flattening out - which is a more healthy and sustainable turnaround, and a good sign of the healthy start to a long-term bull run.

All you budding TAs take note: ignore the MA, MACD and RSI for determining long-term trends, the OBV is the only indicator that unambiguously shows the overall long-term trend.

Watch the bright green line for signs of the turnaround.
