My currect NinjaTrader.mdb size is 53M. It has over two monthes of data from MBT. I have 6 charts open with "Days Back" set to 7. It is using about 250M of memeory. Seems taking a lot of memeory, and it slows down my PC when other applications are running also.
I can control the number of days loaded to the chart (down to 3-4 days), but how do I make the size of the data file smaller? Can I or should I delete the older data from the *.mdb file?
Thanks
