ok, the difference between UTC and GMT is clear, thank you.

The most relevant poin is another Nikkey is traded in new york so ET (not JST).
I should set AssetZone in order to let my script trade that asset when the market is open. This is the point.
Lets try to recap my vps is located in London (lets say GMT) connected to a Server GMT+2 and the script need to trade several saaset one of them is Nikkey225 traded in New York-

BarPeriod = 240;
...
AssetZone = ET;
tadeThatasset;

is that all?

check this example in case you did not already, I think it corresponds to your case from what I understood, it is in Zorro manual under AssetZone, AssetFrame,...

// trade two assets with different time zones
BarPeriod = 60;
FrameOffset = 9; // trade both assets at 9:00 of their local time
while(asset(loop("EUR/USD","USD/JPY")))
{
if(strstr(Asset,"EUR"))
AssetZone = WET;
else if(strstr(Asset,"JPY"))
AssetZone = JST;
TimeFrame = AssetFrame; // use a daily time frame changing at 9:00 local time
...
}

If the asset you want to trade is listed in NY then indeed you will have to use ET time zone.

yes that was exactly the beginning of all my confusion.
I hate that script ahahahahha

In particular TimeFrame = AssetFrame drive me crazy!

Hi,

Just wanted to point out that UTC and GMT, are always the same. UTC is just the modern name for GMT. IRC GMT was tracked in the UK, and UTC is tracked by atomic clock somewhere else.

But the important thing is that UTC and GMT are the same, as they both reference the same timezone which is the time at the Greenwich Median in the UK. Which is the basis of all time zone measurements around the world.

So if the data is GMT +2 it will be the same UTC +2.
