I would like clarification about how historical data is obtained for the periods when NinjaTrader is not connected to the live data connection.
Some providers state clearly they do not provide historical data, but when I load charts, recent history appears. When I disconnect and re-connect the next day, data since the last connect is loaded. If it is not coming from the live data supplier, where does it come from? How can I find out what historical data is available from that source?
I am interested in cash index data (SP500, DJIA & NDX), but I need data without gaps.
I use AMP / CQG.
I also need many years (at least 10 yrs) of historical data, but I understand that may require a specific purchase of historical data. Please advise how to obtain such data.
Thanks
Tony
