is there a software or site that allows you to save es & nq data or charts so you can 're-run' previous days when markets are closed. something like re-running any past date as if it were 'live' so you can re-do the day and review past movements of the market. thanks.
Yeah, eSignal has it, and it works great. http://www.esignal.com/esignal/features/featureslist/6.asp#tickreplay "This new feature lets you download up to 10 days of tick data and play it back at a later time (including while you're offline). You can also pause, speed up or slow down the playback or jump forward by the number of minutes you want or go to a specific time and / or date. You can even change time frames while Tick Replay is running, and the chart will synchronize the plot to the new interval. Lastly, you can set up multiple charts all on different intervals and have them run concurrently tick by tick. Although the maximum number of days you can download is 10, you can still play older files that you will have saved. It is also possible to "stitch" together (using a text editor) previously saved files to create a longer historical file."
