Well I don't really know how much is my max risk ahead of time. I just tell myself the risk is unlimited, and proceed from that assumption. I do options to tamp it down, which works, but doesn't avoid the occasional shellacking. The biggest ones invariably come when I forget to put on the hedge or for some stupid reason decide I don't really need to make it as tight or as large as I normally do. Somehow, the market always knows when you're exposed and punishes you accordingly. But I've always managed to keep the losses to the single digits, percentagewise.
