       * generating the FXT file. On ticks after that, it appears like the
       * left/right are correct but the hi/lo are one tick behind the displayed
       * chart. On the start of a new bar, the hi/lo can be off when a recent
       * extreme drops off but the scale hasn't resized. I tried calling
       * WindowRedraw() first but that did not change results. I don't know
       * about live charts.                                                   */
