Interesting. Just from looking at his activity, I thought it might have been something simpler, like leveraging an imbalance in how the odds adjust on buys vs sells.
Yes that what he's doing, but in very fast automated way, issuing parallel buys of YES and NO, also sells the same way. Tries to sell the same YES/NO shares in parallel.
In a nutshell, basically we have a parallel BUY/SELL problem, and we need to fix it.
