 * Set various token markers based on bar cur/max ratios

 * barId - The ID of the bar to look at the values for [1, 2, 3]
 * barRatio - The ratio of bar value to max value that triggers setting the status marker [0 - 1]
 * status - The name of the status marker to toggle [redmarker, bluemarker, greenmarker, brownmarker, purplemarker, dead]
 * whenLow - The state of the marker when the bar value is <= the ratio [true, false]
