I would like to see how my model behaved during these old days 


Quote from maxpi:
I ran some tech analysis on daily Dow Jones Industrials closes of 1932, got some interesting results, looked like it would have been a tradeable market.

I don't design models for the past. My model is designed once 4 years ago and HAS NO PARAMETER NO OPTIMISATION FOR ANY MARKET FOR ANY TIME PAST OR FUTURE can you imagine that this only could be possible ? 
Quote from Lobster:
I like designing systems that would have worked in the past, since I don't care about the present anyhoo.
Quote from wally_:

Quote from Stone's Throw:
there's nothing as old as yesterday's newspaper...
