I have S&P500 data daily data going back to 1950 in a csv file which would be worthwhile for backtesting longer duration strategies. Aside from breaking it up into years, what else do I need to use it in Zorro?

I couldn't add to this message as a file as it was too big.

Here is a sample of the data as is.

The Convert.c script converts YAHOO data.

That worked perfectly.
