Do you mean that it shows the *new* balance line and the *new* chunk of data (in green)?

What might also be interesting is if you could show both the old and new balance lines -- in this way we could compare how (or whether) the new data affects a strategy's performance.  This would could give us a clue as to how often to update the data set and, also, how big a chunk of new data is required in order to really make a difference. 

Better yet -- to also include before and after SQN or sharpe ratio?  I don't know -- it would be interesting to learn whether new data improves the statistics and by how much.  It is also possible for new data to generate a worse strategy -- and it would be nice to be able to detect if / when that occurs.

Thanks...
