Back testing in Winter and Summer

[dominic]

Hi,

I am trading with IC market broker. MT4 at summer has GMT+3 and Winter is GMT+2. I want to do back test for 1 year. Which UTC I have to select in Adjust TimeZone list when export data for summer and winter ? Please help.

Below is information i received from IC Market broker:

Please be informed that on Sunday the 1st of November, 2015 IC Markets Metatrader 4 server time will move backwards by one hour from GMT +3 to GMT +2. This change is to reflect the US Eastern Standard Time change taking place on the 1st of November, 2015

IC Markets Metatrader 4 server time is based on “5 pm New York”. As the time in the US will move back by one hour IC Markets server time will also move backwards to reflect the change.

How does this change affect you?

The time in the market watch window will now be set at GMT +2, depending on your time zone you may also notice the market open one hour later on Monday. The charts will still show an opening time of 00:00 platform time. Some EA’s using a GMT offset may also be affected by this change, you should make the necessary adjustments to the GMT offset in your EA settings prior to the 1st of November.

The GMT offset explained

The market will close on Friday the 30th of October at 20:59 GMT, 23:59 platform time. New trading hours will start from November 1st 2015, these are listed below.

Hi Dominic,

If your broker is using "5pm New York" time, then please select this from the "Adjust timezone" box (it is towards the top of the list). This will automatically adjust all the dates and times to this time zone, including adjusting for daylight savings (i.e. "Summer/Winter").

Regards.

Hi,

I downloaded data for back testing. As i know news releases at difference time for winter and summer. Should i do back testing separate for winter (from Nov to March next year) and summer (from Mar to Oct) to build 2 set of parameters or just build 1 set parameter for whole year ? Please advise.

I have just bough license of tick story version 1.7. Can I use data for back testing with MT4 build 950 ?

Hi Dominic,

If you intend to be changing your EA parameters between summer and winter, then it would make sense to test them with the separate parameters.

You will need to roll-back to Build 910 since Build 950 is not currently suitable for back-testing. See this thread for more:

Hi,

After i did back testing with MT4 build 910, model quality is n/a (not 99%). Is this correct information ?

Regards.

No - you should be getting 99% modelling quality. Please check out our FAQ to trouble-shoot this; http://www.tickstory.com/forum/viewtopic.php?f=2&t=613.

Thanks.

I got 99% quality.
When I do back testing on MT4, I have to enter spread information same with spread i saw when export data from TickStory to MT4, right ? ( i had ICMarket.mt4config from your EA generated and save as default configuration)

Hi Dominic,

If you are using Build 910, you simply select the spread in the "Spread" combo box in the Strategy Tester.

Thanks.

Do you know which GMT of FXCM broker ?

Hi Dominic,

Your broker will usually publish their GMT offset on their website, so I would suggest either doing a search or asking their support team.

Thanks.
