The setup is NT7, v19 running on a Market Replay connection.
If I instantiate a strategy from a chart with the "Strategy" button and run it, it provides OnBarUpdates for each of the historical bars in the chart, which is expected.
If I instantiate the same strategy from within the "Strategies" tab of the Control Center and run it, it gives OnBarUpdates for each of the historical bars in the chart, then starts over and gives OnBarUpdates for every historical bar a second time, except these report the "Historical" property as "false", and my strategy evaluates them as if they were non-historical bars.
I'm not sure for what reason it would evaluate historical bars twice, or behave differently from starting the strategy from a chart, so I presume this is some kind of bug.
