Property 'IsTickReplay' and Playback with Market Replay

[poseidon_sthlm]

Hello!

I'm testing a custom order flow indicator in Playback with Market Replay data and try to separate the logic for real time data and Replay data in OnMarketUpdate(). I thought I could use the property Bars.IsTickReplay, but it seems to be == false for Market Replay data (unless you tick the box 'isTickReplay' on the Data Series properties.) Is there a way to check if the chart is run by real time data or Market Replay data?

Take a look at Connection and ConnectOptions.

Perhaps one of the various name properties will identify
the Connection as a 'Market Replay' connection.

Hello poseidon_sthlm,

You can check if connected to playback with:

if (Cbi.Connection.PlaybackConnection != null)

You can check between real-time and historical from the State property.

Thanks for the advice on using 'Connection' to check if connected to playback.

When I'm running my script connected to PlayBack, then Bars.IsTickReplay == false and State == Realtime for MarketReplay as well as Historical data. Is this expected?

I recall that my script did work as expected a few years ago. So I wonder if it is correct that Bars.IsTickReplay == false when I run my script in PlayBack with MarketReplay data?

Hello poseidon_sthlm,

It would be expected that Bars.IsTickReplay is true if Tick replay is enabled in the Data Series window. It will be false if this is not enabled.

Tick replay only affects historical data. Playback does not enable this automatically. Using Market Replay for real-time data, which is not historical data, also does not enable this.

Ok, thanks for the video. Much appreciated! This is what I also see when I'm testing my script.

I still would like to separate the logic in my script for PlayBack with Market Replay data versus PlayBack with Historical data. Can this be done?

Hello poseidon_sthlm,

Historical data will load and process before the playback starts.

If you are asking about the playback data type, I'm not aware of a way to detect this.
