Hello ntmehdi,

Thanks for your post.

Market Replay data is deleted after 90 days. This means that you are only able to download up to 90 days of Market Replay data.

To download Market Replay data, you could use the Tools > Historical Data window.

If you want to use more than 90 days with Playback, you would need to download Historical Tick data to use with the Playback connection.

See this help guide page about the differences between Market Replay data and Historical data with Playback and how Playback works: https://ninjatrader.com/support/help...ePlaybackWorks
