I've noticed that for some reason Updated notifications are not triggered in research notebook for custom python indicators. After doing some digging I found out that you do not support this functionality yet. Is there a plan when this would be added?

For anyone who encounters the same issue, I have nicer workaround than the one suggested here: 

You can use decorator set for the Value and notify the subscribers like this:

@property
def Value(self) -> float:
	 # set the self._value to some default value in the constructorre
    return self._value

@Value.setter
def Value(self, value: float):
    self._value = value
    if self.IsReady:
        self.NotifySubscribers(IndicatorDataPoint(self.Time, value))

@property
def IsReady(self) -> bool:
    # add logic to check if the indicator is ready
    return True

# use this method to subscribe to notifications
def Subscribe(self, callable):
    self.subscribers.append(callable)

def NotifySubscribers(self, data: IndicatorDataPoint):
    for subscriber in self.subscribers:
        subscriber(self, data)
