May Silver looked bound for at least 13.205 when the bell ended Friday’s session, but the rally will probably need to do a smidgen better, surpassing a prior peak at 13.260, to rattle the nerves of shorts.  The would refresh the bull trend on the hourly chart and set the futures on course for a test of the 13.885 peak recorded on March 23. A two-day-close above that number would significantly shorten the odds of a thrust to as high as 16.005 by mid-May.
