Zeev's Turnips Patch-No Politics (ZEEV)

[mish]

I believe it is impossible to know.
The MM knows whether he is long or short but the numbers themselves offer no real indication.

The best one can do is ASSUME it all averages out which could be a poor assumption.

Just like the spike in the PC sometime back that was due to a wierd bullish calendar spread, but unless there is direct evidence like that, or unless an until the MMs are forced to show short data (even on options) we will not know. Rest assured someone does but never us IMO (except perhaps on an "unusual" single trade basis)
