MT4 session time plot

I'm using the MT4 demo from FXDD because I'm 'In Search Of...' a new broker. I'm just getting my feet wet with the MT4 language and I've got 'another' question concerning time of day. I like to look at the London session trading range from about 3am to 7am EST US. On the Virtual Trader charts the time on the charts is set to EST US. On the FXDD charts the London range is from 10:00 to 14:00, I'm not sure what the server time is set to with FXDD. My first coding attempt will be an easy one. Plot a vertical line at 10:00 and 14:00 on the FXDD chart, that's it. If that's all I want to do, plot the vertical lines exactly at those times, will I still need to have to adjust for any time zone, GMT +/- whatever, since the 10:00 to 14:00 is the London range on FXDD's charts? If someone has already coded something simple like this where the only input I would have to change is two time variables can you lead me to that?

Thanks

Have a look in http://www.forexfactory.com/forexfor...ead.php?t=5913 and in the indicators archive you can find Akuma99 Atmosphere.mq4. Afaik it plots different sessions on the chart with different background color. Also the code my help you nail down your code.

I think you don't have to adjust by any offset if your broker London's open is at Xam and you put a vertical line at Xam, since MT is always using the server timezone.

wow I'd forgotten I had written that one, I think from memory it was still a little buggy, but the basics are there that should help you with your indicator. The adjustments will depend on your brokers server time, not where you physically are.

Thanks guys....
