Quote from Lawrence Chan:
I actually figured out some possible solutions, maybe you guys can suggest that to your government representatives.
1. Limit any single party's total market exposures to < 5% of average daily volume.
The gang that pushed prices' around is winning (after some work on the tick data), is that they have the ability to completely offset the combined daytrading capacity of all other players plus 10 to 15% more.
2. Forced disclosure in real-time, in the tick data stream, these firms' net open position on every trade they make.
#1 remove any entity the ability to corner the stock market
#2 let everyone to ride on their coattail, thus cancelling their effect completely
