A note on multiple leg option orders(straddles,butterfly's etc). Correct me if I'm wrong, but to my knowledge, no autoex(automatic execution exchange system) will accept multiple sides of option orders and execute them at the same time. If you have
a web based browser trading platform with order entry for multiple orders(straddlles etc.), then your broker is sending your
orders to a floor broker for multiple leg execution . Straddle's and all multiple leg option orders should be executed at the same time since lifting a leg may result in a substantial loss in volatile markets. A number of firms I know have multiple leg order entry
(browser based) for option spreads, including R.F. Laffertey,Benjamin & Jerold and Mr. Stock. I am not familiar with IB or Preffered, but I hear their option execution is very good . I
would suggest that no trader try to execute each side on an exchange auto-ex since if one side is broken(by exchange or MM),
you may have a substantial loss. If you do leg out of spreads,
leg out 10 contracts or less at a time on exchange auto-ex systems. At Lieber & Weissman, we execute on the ISE auto-Ex
with very good results. I welcome any comments from other traders. I also have a free option analytics on my site at
