I'm very aware of scalpers and I'm actually surprised we've been able to operate without this problem for 7 months. I have made alot money from sports arbitrage betting for over a decade but I've never tried to make penny's on super low volume markets as it seems like a waste of time when there is easier money and more to be made elsewhere.

I think i have a grasp on how the market works and the problem could be easily fixed by closing the spread with a 99.99% buyback wall in place.

Thanks for the feedback.
