from bottom to top took 10 hours.
That means I guess that from top to bottom it will take 10 hours too in this case.
So around 17.00h it will be at the bottom according too the 11 januari-chart.
There you can nuy savely (but be carefull, maybe it turns up earlier, we've seen it before).
Trading on the way down is possible too but very difficult I think.
It's not doing EXACT like the januari-chart.
So be carefull.
