Hello schattencheg,

Thanks for the reply.

The message means that you will need to add a 1 tick series to your strategy, then fill your orders on that series. You can add the data series with AddDataSeries.

To submit orders to that series, use the special Entry/Exit methods that take a BarsInProgress parameter:

For instance, EnterLong has this method overload that you would use:

EnterLong(int barsInProgressIndex, int quantity, string signalName)

If your 1 tick series is the second additional series added, you would use 2 for the BarsInProgressIndex.

Please let me know if I can assist further.
