Did you mean Interactive Brokers not Independent? With Interactive you would probably need to have $2.50 in cash in your account per share to short ECOB - shorting even $5,000 worth would probably require around $150,000 as collateral and you would pay some crazy Apr rate of probably 300% daily on your position.
Sounds like a plan :) That would be the day they rollout into a few hundred stores with a new funder and you forced to cover at the open of the market at 6 cents- Then you would really hate Conboy-lol
