I am located in US MST and trying to make sure the London 8am open is displayed on my charts properly esp during the couple weeks when US is in DST and London hasn't transitioned to BST. How do you have it set up?

For example if I want to see the Brent or Euro 8am london open how do I set up the chart settings and set up the global symbol settings?

I tried to set the session times in global symbol settings to London(+0)/BST(+1) then use a chart in MST but it doesn't seem to be handling the time change properly.

Thanks

I can't offer specific advice, other than to say I personally set all my charts to show Eastern time, even though I am not in that time zone and my computer clock is not in that time zone. It's a personal preference, and one that I am glad Sierra supports. You could do the same, or set whatever time frame the instrument you most often trade is located in, and the charts will show that local time regardless of your computer time zone.

I do what Mike does, and that timezone is set in Global Settings >> Data/Trade Service Settings. This setting ignores your computer timezone setting, and the Chart time will follow this timezone. I didin't need to make any changes to the Symbol Setting's timezones, but you may need to.

Here are some documentation links:
Time Zone Setting - Sierra Chart

Global Symbol Settings - Sierra Chart
The following is from the above link:

"Intraday >> Time Zone: This specifies the time zone for the Intraday chart Session Times specified on this tab of the Global Symbol Settings window. For example, if the Session Times are defined in New York time, then this needs to be set to the New York Time Zone. This does not have to match the Time Zone setting in Sierra Chart. When these Session Times are applied to a chart, then the Session Times will be converted from this time zone to the Time Zone setting in Sierra Chart.

You should specify what Time Zone the Session Times are relative to, by selecting a Time Zone from the list. In this way you can always be assured that the correct Session Times will be set even if you change the Sierra Chart global Time Zone setting. Otherwise, select Not Specified (this is the default).

It needs to be understood that this Time Zone setting does not specify the time zone that you want times displayed as in the charts for the symbol that this setting is for. Sierra Chart has a single Time Zone setting set through Global Settings >> Data/Trade Service Settings that sets the Time Zone to display times in. This setting only indicates what Time Zone the Session Times set in the Global Symbol Settings for the symbol, are relative to."

Hey guys thanks for the responses...this is what was confusing me...note the different 8am opening price on Mar6 which is the day before the DST change.

In the global datafeed setup I am set to MST (where I am located).

For any contract I trade I setup the session times in the global symbol settings to the domicile timezone of the contract. So for Brent I would set the session times to London(+0)/BST(+1). I know @Fat Tails has also talked about using the domicile timezone for contract session times to properly display DST/BST etc.

I just want to make sure I am looking at 8am London during these 3 weeks when London is not on BST and historical intraday data is correct as well.

sorry if my explanation is confusing...I tried to explain over on SC support board but that didnt work well.

You can see in the attached charts the different 8am open prices on March 6....which is correct?

After the DST change and starting Mar9 the charts are the same.

Did you set the timezones to London in both the Global Settings >> Data/Trade Service Settings and the Global Settings >> Symbol Settings >> Intraday tab?

The Session Times in the Chart Settings follow these settings, not your MST timezone.

Hey Tom

For "Global Settings >> Data/Trade Service Settings" = Denver (MST -7/ MDT-6)

for this futures contract I have "Global Settings >> Symbol Settings >> Intraday tab" = London (+0 GMT/+1 BST)

The chart on the right is using the above default settings...

The chart on the left is manually inputting 8am in the "chart settings-session times" and then changing the chart timezone to London in the "chart settings/advanced settings-time zone" box.

The Brent contract was originally attached to the International Petroleum Exchange (IPE) in London. Meanwhile IPE is part of ICE Futures Europe. The probleme with the Brent Crude contract is that New York and London have different daylight savings schedules. Most of year the time difference between London and New York is 5 hours, just for the periods

-> Sunday, March 8, 2015 - Saturday, March 28, 2015 (3 weeks)
-> Sunday, October 25 - Saturday, October 31 (1 week)

there is a time difference of only 4 hours.

There is a circular issued by ICE Futures Europe, which explains the trading hours and settlement periods during these two periods. In fact the Brent crude contract follows exclusively New York time. The reason is pretty simple. Daily settlement of the Brent crude contract is done at the same time as the daily settlement for the NYMEX traded WTI contract.

Therefore you cannot run the Brent Crude contract on London time. You need to set the session template to US time. Please read the circular and attachments issued by ICE for further details:

Thanks for the info Harry...my concern is having the proper 8am (or any time) properly represented during the DST/BST transition.

Ok so maybe Brent was an odd choice for an example but lets say I use the 6E or cash EURO and want to track the 8am London open...I just want to make sure that during these DST/BST transitions I am looking at the right time using the domicile session templates.

The reason I dragged you into this Harry was I wanted to find out if NT7 will display the right session open during these weeks and still have the correct times for historical intraday data prior to and after these dates.
-> Sunday, March 8, 2015 - Saturday, March 28, 2015 (3 weeks)
-> Sunday, October 25 - Saturday, October 31 (1 week)

Using the NT7 domicile session logic doesn't seem to work in SierraChart....they have told me to display the chart in the Local time for the correct open. So to properly display the 8am London Euro open i need to put the chart into London time.

Sorry for the ramble...
