Thanks jcl, and now swingtraderkk!

jcl, yes, I realized from the start that 100% loss was possible, and didn't start trading Real until I'd Demo'd to a point of some satisfaction. However, I'm still uncomfortable because I don't feel I yet have a good understanding of the likelihood of that 100% loss, or 50%, or even 25%, nor how to best protect against it, preferably in an automated way consistent with the theme of Zorro.

swingtraderkk, I think your distinction is somewhat useful. On the flip side, though, there need to be ways to determine and manage the risks - I don't see that as any less necessary because of an income vs. capital distinction. I hope no one is putting 100% of their capital into any single thing - be it a Zorro strategy or whatever! Whether for capapp or income, we're putting some portion of our capital at risk. Without RM as acidburn tried to point out we're gambling - worse even, 'cause at least with gambling you can compute the odds.

Thanks.
