Donchians and other stuff

Hi,

I am looking at Donchian breakouts using Oanda as my platform (yes, I am using the demo :rolleyes:). I am based in the UK, if I am trading EOD (i.e. daily bars), do you think I should leave the time of the daily bars open as 0:00 (system default), or would I be better off changing it to 06:00 (UK market open)?

What do you reckon?
