This is a very long shot, but there seems to be a good correspondence with a fibonacci sequence an the time at which these retracements are occurring. Based on time analysis I have looked at how much each wave has pulled back using the Fibonacci for the price. Based on this it seems that each wave pulled back between 30/50% before going up again. This gave me enough information to draw an elliot wave to roughly estimate the expansion pattern 1 to 5 then a zig-zag, 1 to 3 pull back. Looks like the price might pull back another little bit from where we are, then will start pumping back up toward 20K
