I do not believe there is one. If your looking to minimize taxes on gains you need to shoot for 1 year + buy and hold for long term cap gains and/or futures markets I believe are taxed in some adventitious way. I play with significantly less funds than you and am blessed with all losses on MU so I wont have to worry about taxes for the next couples years so I do not spend too much time looking into it. With that said... you should as 15-30% tax on ~250k in gains is 37.5k.
