The chart is logarithmic.
We can observe a 5 wave decline from the last peek at 4856 followed for a more slow upward movement that
I can't precise due the lack of historic if its a new impulsive fase or part of something else.
The chances are more inclined to the impulsive due the extension of the 3dr wave (even when the C wave in zigzags could reach more than 2 to 1 proportion with the A wave, is far more common to find this kind of extendend proportions in waves 3 and there fore this have more chances to be an impulse.
In this the wave 3 is near to its finish, so in the short time (this is a weekly chart) is probable that we will face an important pullback but the odds in favor to new highs in the long run.
