Changing Session Begins and Session Ends time

[forexample]

Using the chart properties, I have the "day break line" on my charts.
The default "session begins" time is 12:00 AM and the "session ends" time is 12:00 AM.

I live on the west coast (Pacific Standard Time) and want to change the session begin and end time to 9:00 PM so that it will correspond with 12:00 AM Eastern Time.

When I change the begin and end time to 9:00 PM and then ckick on the "Apply" button, the chart goes blank and all the data disappears.

Can someone tell me how to successfully change the session begin and end time to 9:00 P.M?

Thanks.

Unfortunately you cannot do that. You could set it to 9am to 9pm if you wanted to though. 12am to 12am is generally equivalent to 9pm to 9pm because they are both 24 hour periods.
