I'm not sure if this is a bug or something I'm not doing correctly. Since there is only about a year of daily historical data on the historical server I have got hold of 1 minute forex files going back 10 years. I then converted these files into NT format and imported them into NT7 with the "Generate Daily Bars" option ticked. So far so good, I now have 10 years worth of data on my daily and weekly charts.
However here comes the problem. If at any time on my Daily or Weekly chart I want to refresh the current data and choose Reload All Historical Data, it goes and totally wipes out all my underlying imported daily bars. I can't see a way around this at the moment as I need to use the Reload All Historical Data every couple of days as some times I will get disconnected from my broker feed and it causes an incosistency on the current live bar. The only way I know to fix this is to use the reload option on the chart. However this in turn goes and clears all my daily bar imported history.
Any ideas?
