Post From: DAX Mini - Incorrect bar start time during Daylight Savings for some bar periods.

Hi John,
Thanks for your reply. I read the information you pointed me to and I believe I have all my session times correct as shown in attached pics.
Symbol settings are 01:15 to 21:59:59. Time zone is UTC +1/+2. Global time setting is set to the same as are the chart session times.
I have provided a pic of a 60 minute chart which starts at the correct time ie 02:15 and the same chart but bar period changed to 40 minutes.
The start time is now 01:55 (20 mins earlier) NOT 02:15 - the correct start time.
This of course makes all the following bars incorrect for the 40 minute bar interval.
The last 40 minute bar has a timestamp of 21:55. This is the same time stamp for non-daylight saving. With a start at 01:55. If it starts at the correct time the last bar stamp should be 21:35.

As mentioned previously the time stamps for 40 minute bars are correct during normal time.

I think this problem is exists because the DAX starts trading an hour later during DST but it stops at the same time. So during DST it trades one hour less. Unlike any other market I have encountered.
SC has all the time stamps during DST the SAME as during normal time. This is incorrect as during DST they are offset by one hour. As follows.

DST OFF   01:15:00 01:55:00 02:35:00 03:15:00 03:55:00 04:35:00 and the last few bars   19:55:00 20:35:00 21:15:00 21:55:00 and stops at 21:59:59

DST ON   02:15:00 02:55:00 03:35:00 04:15:00 04:55:00 05:35:00  and the last few bars 20:55:00 21:35:00

and these are the DST time stamps from the SC chart.
DST OFF   01:15:00 01:55:00 02:35:00 03:15:00 03:55:00 04:35:00  and the last few bars 19:15:00 19:55:00 20:35:00 21:15:00 21:55:00

DST ON   01:55:00 02:35:00 03:15:00 03:55:00 04:35:00 05:15:00  and the last few bars 19:55:00 20:35:00 21:15:00 21:55:00. All these time stamps are the SAME as for normal time which is not correct.

Thanks
Peter.
