BackTest Timezone

This thread seems to have drawn a blank on MT4 avenues for a -5GMT or better to get better returns on the same trade. How about ECNs then? Are there any that operate in the timezone needed to improve the edge for traders?
I'll get a list of ECNs and see what we come up with, unless someone is already on this.

Why did I go down this path of enquiry when it is useless unless you are getting a feed into your charting from the ECN? Derrrrr!!!

I think this is interesting too. Wouldnt daily candles normally be expected to open at 17:00 EST? The FX market opens and closes at 17:00 EST, that is when positions are rolled over, so am I correct in suggesting that this should be considered the "market standard" or "most common practice"?

Thanks!
