Is it possible to not save chart data in data base?

[ellefk]

I look at a lot of charts and would like to not save the data for the Charts in the data base. Is that possible?

Hello ellefk,

Unfortunately, to display data on a chart, this must be downloaded first.

It is possible to prevent NinjaTrader from downloading historical data automatically, but this would also prevent the historical data from displaying on a chart.
(Tools -> Options -> Market Data -> Get data from server)

To remove any old historical data that is unneeded, right-click the instrument or date in the Tools -> Historical Data window and select Remove.
