How can I see unrealized loss if I am not a subscriber? Do you include it in the Hypothetical Monthly Returns?

The main point here is that all the 'unrealized losses' you see are already included in the strategy page (even if you are not subscribed to it). This means that unrealized losses were included in all the results that were reported, including:

The system equity chart
The monthly returns table (above the chart)
The return statistics

We include 'marked-to-market' profit-and-loss in all reported data. Otherwise, it would be possible for strategy developers to 'hide' their losses by simply never closing a position! This is not really acceptable from a Generally Accepted Accounting Principals (GAAP) perspective. C2 always includes marked-to-market losses in the data it reports to non-subscribers.
