I have been using NinjaTrader with OpenTick for displaying the CME:ES charts. I notice that it can take a very long time whenever it has to download new data. For example, when I first open it up and select the 5 minute chart for the past month, it can take as long as 10 minutes to fetch the chart. I am not using the registered version of NinjaTrader...is this lag intentional trial limitation until I pay for the software? Also, is there a way to have it save the historical data so that it only has to be downloaded once? Oh, and I should remark that I have been checking my internet bandwidth and it's not actually downloading the entire time. Not sure when it starts up, but the connection is using no bandwidth for at least the first minute after I request the data.
