RAS,

assuming the "other data" is just another market, all that is required
is to use my modified version of GT::Prices. You can then load the other
market and use it whereever you would use Prices of the original market.
When graphing, you can either graph that market instead of the original
market via Prices, or you can not show the original market via
--type=none and only graph indicators depending on the alternative
market. Of course, you cannot use volumes from the alternative market,
so you need to graph with --novolume.

I do not think any change to the data sources is required unless you
need the volume of the other market, or you need to use that other
market in various timeframes beyond just the timeframe of the primary
market.
