I have transact data feed... When i download the historical chart fron DTN everything is ok.. but when i start the data feed (back ìfill automatic) the price creates a longer bar. I look a 30 constant volume bars). In other words the chart is over position...and to reach the last traded price it makes "a jump" with a longer bar..(about 5-10 pips). Holidays file is ok... Session as well seem ok.. Can someones help me please? tks
