Which worked fine , but the snap shot doesn't .
It looks like it could use one more ..... ) ......

T2020, you would need to pass a dataseries to the SMA, not a double (no index after the Middle) -


SMA(Bollinger(1, 30).Middle, 20)

So , just that one set of brackets basically . Not sure I'll ever make it as a

Yes, without choosing to retrieve an index value a dataseries is passed to the SMA - when you apply an index you retrieve a double value of the Middle dataseries...this generated the error you ran into, an SMA needs a history to calculate thus a dataseries is expected.
