Y Axis

The Y axis ranges from negative values to positive values with a zero line approximately in the middle of the range. The Y axis metric is dependent on the options chart study you display. The Y axis can display any of the following studies:

The Y axis label is displayed in the upper left corner of an option chart window (see figure). By default, all option chart windows are P & L, or profit and loss (total). If you change the Y axis, the label changes to identify the selected Y axis metric.
