So, I finally added support for building simulation models with multiple quote streams inside of Trade Miner. Why is that the least bit interesting, you say? Well, now, you can base your trading logic off of movements and trends of something other than the item you are trading. For instance, if you load in the price of gold as a secondary quote stream, you could test out shorting an index fund when the price of gold spikes (or vice versa). Or, if you want to get crazy, you could load in data regarding snowfall and temperature and try to use that in a strategy to trade the stock of a cold weather clothing provider.
You can also now plot the “moving beta” of a stock. Just use the Beta indicator and associate the asset and market quote streams to view how the beta changes over time (I would recommend using 12 periods of monthly data with something like an S&P 500 index fund as your market data). Currently, alpha is derived from the linear regression, but a future release will likely allow you to specify the risk free rate to use.
