Till now, I have downloaded data for say ES ##-## for 13 months, from 13 July 2011 to 10 Aug 2012.
Now, that is on 11 Aug 2012, when I am trying to load the 150 tick data for ES ##-## on chart for a year, it seems that, instead of loading the data from already downloaded historical data, NT downloads the data from the data provider and loads the data on chart as NT takes too long to load the data on chart.
Please let me know how to make NT to load tick data from historical data and not download the data once again.
Thanks and regards.
