Attention!

Hello, I have a question on the workings of stop/start strategy from the strategies tab: if I start a strategy after using RightClick-> New Strategy I undestand the Initialize() is executed, and the OnBarUpdate() is ready to be triggered and being executed.

Now what happens if I stop a running strategy and start it again by pressing the start button? Is the Initialize() member function executed?

In other terms, if I stop and start the strategy, do I get a new instance of the object, or is it still the same, and therefore Initialize() is not executed?

Thanks

You get a new instance.

Do you mean that when pressing start (after stopping) Initialize() is executed and the variables are reinitialized?

No. You can see when Initialize() is called by adding a print command into it. You should not be placing variable initializes in there. You should do that in the Variables section of the code.
