It was not my opinion but jcl's. For me it's more interessting what comes closer to reality. If a strategy includes calculations based on open and close prices of a bar and without EXTRADATA both are simulated I guess setting this flag includes the real prices - so I think setting this flag might be more realistic in this case. But maybe I didn't understand it, as said, I'm not sure.
I know - I hope he'll read it here eventually
And I agree with the rest you wrote - seems like with the flag the results should be more realistic. Because of that I would prefer if it was default (implicit). IMHO this new feature has potential to cause lot of confusion in the future (and among new users).
