Using Gann's theory, watch for 30, 60 and 90 days cycle. You can see from my dates noted on the turns, Wesfarmers has been turning on 19th of every month as shown in the chart.
Also another to support this turning point, from the March 19 low to the top on April 19, it's 31 calendar days, and another 30 days down to 50% retracement - May 19.
Should be expecting a turn up from May 19 onwards.
