Hello Murphy67,

This error can happen when switching from Playback to a realtime mode and not re applying the strategy. If you are using playback, please make sure to remove all strategy instances once connected to the realtime account and then re apply the strategy to the correct account.

If that is not the situation you would need to reset the database, you can use the control center -> Tools -> Database menu to reset the database.

Hello Murphy67,

I reset the database and reload the chart.

Did you use playback after doing that? The error message you provided is only known to appear for the use case where a playback strategy is reused in realtime. When you are in realtime are you applying a brand new instance of the strategy and then seeing an error? For example there are 0 strategies listed in the control center and then you apply a new strategy.

Now, last bar at 9:00 next bar at 09:45?

From the chart it looks like you may need to reload historical data.

Hello Murphy67,

If you made a new post then that went to the reply queue for the area which you posted in, someone will reply to that when we get to that point in the queue for that area. The data question would be separate from the error you are asking about here so that would be the best route anyway so that we can resolve the error/original concern here without going into side issues.
