Quote from opt789:
I am very familiar with trading SPX options, both small and very large orders. Brokers like IB and TOS will not let you talk to a broker in the pit, they will take your order and then call their broker who will get a market. The SPX is one of the few remaining monopolies and the market makers exploit it to no end. They will steal your money if you let them, and they will laugh at you afterwards (I used to be a market maker so I don't have a problem telling the truth about them). Virtually all of the people on this board have no idea what will happen in a real fast market, I can assure you that if one eventually does happen again you will get a fill so bad you will want to sue, but you would lose so don't bother.
The suggestion of making the order as delta neutral as possible is a very good one, then when you get a market of 1 bid at 2 you can leave your 1.75 bid in and wait to see if you can get filled. Remember that the SPX market makers are your enemy and they have a complete and total monopoly that they wield without any compassion.
If you are a large serious player you can get a broker to work your order as best he can but you have to pay extra, and the bottom line is the market makers are going to do whatever they want anyway.
For what it's worth, I switched from SPX options to ES options because I became so fed up with the SPX guys. ES options have become much better than they used to be - my gratitude to Atticus for pointing that out to me some time ago. ES options are .50 cents wide all day for at the money while the SPX is 2 dollars wide, which is better for you?
The only useful thing left about SPX options is you can sit and watch small retail orders languish out there while the market makers lean on them, and then pick them off before they do.
If I haven't talked you out of SPX options by now, I have some beautiful swamp land I would like to sell you.
Is it that bad trading SPX? Is there no competition between market makers for getting orders? For example, if I want to Sell a Vertical Call Spread 100 times with a market of .7 / 1.00 I would place it at .85 and see what happens. Perhaps lowering it to .8 but I wonât give more. Another question, for example the above mentioned spread should have a market of .8 / 1.10 is it possible they quote it at .7 / 1.00 because the Market Makers have the âfeelingâ you are selling (like with Iron Conders)?
I have been trading options for about 3 yrs now and Iâm very profitable trading the so called âincome generatingâ strategies. Of course there not income strategies, Market Makers donât give away free money. Although European market have been very volatile (in January it dropped 15% in just 2 days) my max. drawdown in the last 12 months is about 3%.
