ZCK3 moved above 713 but so far it has failed to find support and it's trading now at 709. A daily close and follow up for few days above 713 will indicate a trend change with 713 as the "switch".
In the previously posted pic there's a date "4/3/13" and right before that date there's "3/30/13" vertical Fib. (not shown for simplicity) In other words, from 3/30/13 to 4/3/13 is "important" time window. Another confluence with that time is 651 to 659 S/R cluster that may have something to do with that 3/30/13 to 4/3/13. In my chart I'm showing 624 at 4/3/13. Will see, the market has the last word and in due time will show us the way.

Moving and closing above "The switch $713" voids the above.

ZCK3 now trading at 708.75
