It would be helpful for SQX to compute these kinds of summary statistics in real time and visualize them in a row at the bottom of a databank. It would be interesting to see these values change as the build runs and as new strategies are inserted into a databank. Summary statistics of a databank could include mean, max, min, stddev, etc of a column and could be user configurable.
I know it's possible to merge strategies into a portfolio and then inspect the 'portfolio' column values, but this requires stopping the build, creating a portfolio, and defining a custom databank view (to inspect portfolio values).
