ot-cab, I don't know if there is group ins for traders, since I still work full time, but if not, it would not be a bad side job for someone to put something together. The person who has the time, desire and knowledge to do so, could probably make enough $$$$ to withstand quite a few losses. On the other hand, it would be counter productive as far as trying to trade full time.
If, on the other hand, you cannot find anything, you may want to look into joining your local Chamber of Commerce. Many local Chambers do have group ins plans.
