How can I refresh the quote data for an existing profit and loss chart?
Click the “refresh” link in the upper left corner of the line graph. This will refresh the last trade price for the underlying. If you’d like to refresh the option prices also, please be sure to click on the lock next to the option price field and change the color of the lock to green before the refresh button is clicked. This only refreshes the price data. To reset the chart back to the original data and price point on the chart use the reset button in the middle of the screen.
