Historically when the True Strength Indicator reaches its current level the stock drops a minimum of 1.18% with an average of 5.06% over the next few weeks. I am tracking multiple potential trendchannel support levels and the first level to get hit coincides with a shared support level at 19.83. From the CLOSE on December 30, 2016, movement to this level would equate to a drop around 4.25% which is very realistic.
