+NOT_ENOUGH__EVERY_SLIDER_CLICK_WHOLE_BAG_MOVES_DOWN

TODO Save datasource must fully unregister consumers and register again to avoid StreamingSolidifier dupes; now BacktestDataSource stays created once with Initialize() => less work to maintain rebirth-style lifecycle  ("here is the problem for a streaming bar to carry another symbol!")

TODO 2/2 still print incoming quote details on "Streaming" surface even though "Streaming" button isn't pressed
TODO add 3rd button
