I have a real time chart (opened clicking on Live data symbol) with several bar (more than 100 bars) and I am collecting real time data

If I manually apply to this chart an indicator like BollingerLowerBand I see the graph, all the historical calculated values and for the last LIVE bars I see a NaN value (correct! because I use CLOSE to calculate the indicator)

If I run an Live System (I am using the example BollingerbandPenetration) and I programmatically

do this in the Startup (having previously declared  Private BBU As BollingerBandUpper):

BBL = New BollingerBandLower(14, 1.5)

BBL.SetInputs(Close)

BBL.ChartSettings.Color = Color.Crimson

BBL.ChartSettings.ShowInChart = True

I see the labbel BBL added to the chart  but  all historical values are NaN

I supposed I have to wait to collect new  14 bars aftert LIVE system startup before having a value.... not true... always nan

what I am missing?

Thanks a lot

Thanks,

The test suggested by Daniel  is OK but does not solve the problem.

If I have a moving average with 100 bars I have to wait 100 live new bars before doing calculations?

and if I close down rightEdge I have to wait 100 new bars again ?

what  to do to force the indicator to use historical bars too?

I have always to add indicators to my trading system  with drag drop and consume internally the indicators ?

Do you have any suggestions on how to make it more intuitive?   What did you expect to happen?  Did you expect the system to automatically calculate the indicator values based on historical data when running in live mode?  Now that you know that the lead bars setting exists, does it make sense to you?

(It makes sense to us- the lead bars are the number of bars of history your system needs before it can start trading, and applies both to historical simulations and live trading.  But what makes sense to us, who have been working on RightEdge for years, obviously isn't necessarily the same as what makes sense to a new user.)

Thanks,
