Have you considered creating a TimeSeries for each data series, and then putting them all together in a dict, keyed by symbol? One disadvantage of one big monster numpy array for all the series is that not all series may have a full set of 1800 data points. So the array isn't really nicely

[Numpy-discussion] Question on timeseries, for financial application

2009-12-12 Thread THOMAS BROWNE
Hello all, Quite new to numpy / timeseries module, please forgive the elementary question. I wish to do quite to do a bunch of multivariate analysis on 1000 different financial markets series, each holding about 1800 data points (5 years of daily data). What's the best way to put this into a
