Triple EMA (50,100,200) is converging again after a cross/re-cross. This appears to have happened 9-15-2017 to 11-6-2017 (~52 days). This same convergence is appearing again (following EMA cross/re-cross) from 1-16-17 to present (~53 days). Fractals have some resemblance but I'm not an expert in that area and could be wrong.
