I don't think this is the case. I think that hour() actually always refers to the UTC hour. The following script: Code: function run() { StartDate = 20150101; BarZone = ET; BarPeriod = 1440; BarOffset = 9*60; vars Close = series(priceClose()); printf("\nhour: %d, lhour: %d, Close: %f", hour(), lhour(ET), Close[0]); } generates the following example output: Code: hour: 13, lhour: 9, Close: 1.109865 hour: 13, lhour: 9, Close: 1.115435 hour: 13, lhour: 9, Close: 1.116505 hour: 13, lhour: 9, Close: 1.120315 hour: 13, lhour: 9, Close: 1.119425 hour: 13, lhour: 9, Close: 1.114395 hour: 13, lhour: 9, Close: 1.108410 hour: 13, lhour: 9, Close: 1.108720 hour: 13, lhour: 9, Close: 1.107920 hour: 13, lhour: 9, Close: 1.118925 hour: 13, lhour: 9, Close: 1.118165 Chart... ok which to me suggests that hour() is returning the UTC hour, while lhour(ET) is returning the ET hour, even though BarZone is set. www.robotwealth.com
