How to erase Plot Executions?

[Lost Trader]

Not sure where to ask this - I record market data & in off-hours, randomly select a day to replay & practice. If I have previously practiced on that day, all the Buy/Sell markers are lumped on the first bar of the chart (since the other bars aren't there yet). Since this is practice, I want to erase that previous practice (both on the chart & in account performance) and start over on that day.

Please Note: I am NOT asking how to hide the plot executions. I am aware of the Chart properties setting that allows me to hide the markers. That is NOT the question.

I wish to erase the executions so I can make new executions during that practice day. How can I do this?

Thanks!

The only thing you can do is reset a simulation account or create a new one to use for this practice session, then delete it.
