I had a situation where after restarting the program it did not connect to the broker, respectively, quotes were not updated, while visually in the strategy monitor all looked fine. So my suggestion is to add a check and if dataset is not updated over time, then somehow clearly signal it.

There's no requirement to keep DataSets updated. In other words, updating DataSets is not required ever, but can make the first run quicker.

WealthLab always* checks for the most recent data when it runs a backtest. If you request data and it's not up-to-date, the "Data Valet" moves to the next Historical Data Provider that is checked in the list to request the data.

* Exception - if you run multiple backtests in the same Strategy Window without changing the Date Range, we don't check for new data. You can force a reload/update by clicking the Bars Loaded message in the status.

I mean for strategy monitor. And in my case it was a linked dataset, so the data was not updated

So as your posts won't confuse other readers, there is no "manager" except the Order Manager - it's called Strategy Monitor.

If we're talking about Polling, then it makes no difference. A linked DataSet is automatically the first in the priority, but if it can't provide up-to-date data, the Data Valet will look at the other checked Historical Providers for the data.

If you configured Streaming in the S. Monitor and the provider cannot connect, then that's a problem you need to solve locally.
