Quote from Lawrence Chan:
Most MMs carry 10 to 15 lines of options per symbols. All basic analysis are not necessary for them because they know options in and out. What they need is the odd (historical volatility) and how the underlying reacting to the scenario.
Thus it is not a matter of which tool is better, it is which tool fits you the best.

Quote from OptionScreen:
Intersting post. Do you mean 10 to 15 legs which is equal
of doing 10 to 15 position transacted?
And where OptionStation.8 stands for it's point of
weakness and advantages? i know they are your
compatitor, but i'm intersted to hear more?
Is optionvue or any others.. are way better tools
to use for option analysis?
Quote from Lawrence Chan:
10 to 15 lines on each side - some lines are net long and some are net short.
Depending on the MM's strategy, the combined position can be viewed in many ways - break that into multiple positions as you say, or a few big combined positions.
For OS8, I have not used that so I do not really know how far it has progressed since I last tried OS1 many years ago
