    market making

    You can bid and ask on the same option. Market makers, however, can do this on every option. In general, non-market makers are limited as to how many markets they can quote.

    Milk ripping!

    It is what we call it when a cash player (in this case Kraft) tries to get in the way of a rally in a feeble manner. It is a reference to the Maginot Line. Tower

    Milk ripping!

    Blocks and barrels are tight, whey is still over 50 cents and Class IV is over 21 in the front. This is pulling raw milk from the III's. Blocks seem to be particularly tight. On both thursday and friday Iowa was able to walk up the cash in blocks without any challenge. Kraft sold a barrel on...

    The Black Swan Swims

    When you are talking about the S&P's options or Euro's a lot of the guys do play for pay. But the majority of us are on our own.

    The Black Swan Swims

    I am not sure what you mean here. Locals almost exclusively trade their own money. Very few money managers work on the floor - at least in the Ag's. Unless what you mean is that most of the guys on this forum trade for funds.

    The Black Swan Swims

    One of the biggest differences I have noticed about locals vrs. off the floor guys is that locals seem to be far more sensitive to day-to-day fluctuations in their net liq. When I get off the floor I do three things: 1) Calculate how much money I made or lost 2) Input my trades and...

    The Black Swan Swims

    Major: I have never considered the ratio you describe. To be candid, I have never even thought about the timing of theta in that way. Because of this I asked the two largest vol. sellers I know about it. One said he didn't do it this way (though he was familiar with it) and the other was...

    The Black Swan Swims

    I agree with much of what you say here (we it "eating like a bird and crapping like an elephant"). With regard to keeping a position concentrated - that is a rather difficult thing for someone to do on the floor. It is fairly straight-forward for someone to maintain both a delta and gamma...

    The Black Swan Swims

    I agree that short vol. is not inherently bad. Rather, that if you are not on top of it when the market turns, it chews up your position rather quickly. Positions do get extremely difficult to manage on the floor - at least during the day. This is only because so much is going on right then...

    The Black Swan Swims

    The trade is the Dairy options at the CME. A fairly illiquid futures market where volatility isn't usually a very big issue. We kind of drift back and fourth - moving 10 points up or down a day. This is not a tremendous loss for him (about 8%) - though it is the largest loss he has yet...

    The Black Swan Swims

    I am relatively new to this forum and realize that most here believe that trading short vol. is the most reliable way to profit in options. I think that trading short vol. requires far more skill than most traders have (or even realize they need). I am a floor trader at the CME. Our contract...

    What's your average trade size?

    Daddy'sboy: I agree it would be quite impressive if the guys we worked with were profitable within the first sixty days. Sadly, that is not the case - or even close to it. Where I work about 1 in 15 options traders survive the first year. As I recall, I started making money after six...

    What's your average trade size?

    Daddy'sboy: We do it on a rolling 12 months and not on a calendar year basis. The closest we have to someone in the position you describe is someone I have started training. I just looked at his position and he has about 5% of his account at risk.

    What's your average trade size?

    A5: I am not sure this answers your question directly but I can tell you that a rule of thumb we use is to never risk more than 1 months profit per day. So, if you make $10,000 per year, we would never have a position on that exposes us to more than an $833 loss in one day. That said...

    Buying/Selling Options

    Major: I, like many in this forum, have read many books on options over the past several years. In my opinion the best author on managing risk is been Cottle. His discussions on risk analysis are superior and his writing style is clear. The book I would particularly recommend is Options...

    Buying/Selling Options

    Bob: When you ask "do we personally know of anyone (ourselves) included who makes consistent MONEY trading options?" I would have to say that I do and most of these guys do not try to employ exotic trading techniques that are unique each time. They simply find strategies that work and...

    Buying/Selling Options

    lindq: I agree that trading options introduces issues that straight futures (or stock) traders don't have to face. However, because you have so much more control over the structure of an options position than you do over a stock or futures portfolio, getting a consistent return from...

    Buying/Selling Options

    pcgeek86: If your broker allows you to sell calls you can certainly sell puts - at least synthetically. (By that I mean that the return curve of a synthetic put will be identical to that of an actual put). If you sell a call and buy a future 1:1 you have sold a put - even if your broker...

    Options and Greeks

    Of course it was a swipe at you. You were being a dick to someone who was simply trying to get information. Trading options is hard and this is a place new folks come for help. If you don't want to provide it - that is fine. But don't try and make people feel stupid because they don't have...

    Options and Greeks

    The four Greeks you are most likely to concerned about as a new options trader are delta, gamma, vega and theta. They are inter-related but not in the way you describe above. Delta: At its simplest, delta measures how much an option will move relative to the underlying security...
