If you did not receive the answer to your question: "What are the chances you need to roll AGAIN before expiration" At the moment you rolled, you know the prob of the short option in the money at expiration (roughly equal to the absolute value of the short put delta). Multiply that by two...

Consider for instance an OTM call option. Price of call for strike K and time T is C(X, T, K), where X is the underlying's current price. We are here interested to the case when the difference between underlying price X and strike k is equal to the call premium. Let us denote K* such strike, and...

Do you buy or sell options? When indicate "buy or sell on volume", which volume are you refering to (options volume, stocks volume, etc/volume)? What is the volume criterion you use? Thanks

Good observation, but how do we exactly make money with this?

If it is true then he is trying to catch yet another tide in human history. Erradicating poverty. What is the problem with that? It is a good purpose. He may be saying let us add a patch to capitalism,which would make a good thing even better. Adding a patch is a well known concept in software...

What I understand from your proposition is that the customer should decide on the trade-offs of price quality, commission, etc, on the tradestation. One thing I want to add is that it may be easy for people to give all sort of logical point of views/suggestions, but one should also consider...

Thank you IBsoft for this response. It is a reasonable and acceptable answer. There are other areas where I like IB. For instance, I do not know of any other broker who give great commission rates for penny (less than 0.05 and 0.10) options. I think that they deserve recognition on this,and I...

This is a thoughful response. I do not have any problem with IB--I did not agree with the response (see why below) that was given by some posts which I do not know whether they reflect IB or not. My point of views were directed at the posters not at IB. All what I would expect is simply a...

This relates to what I also think. Go where there are a lot of buyers and sellers. One of them will be defeated. You ride with the winners.

The high (low) over what period of time? Time is important as it implies the size of the move.

That is the reason why I trade only liquid options with tight spread (QQQQs and IWM). The Penny Pilot program is god sent to the retail customer. The penny (or even pip) quotes should be general to every security in the industry. Those who say it will hurt liquidity I think are saying it just to...

How come you do not see the problem? Here is what I understand him saying: at a time T he placed an order at IB for 6.30. At a time T+(big) Delta, he placed the same order with another broker for 6.30. He got filled with the othe broker (who received a similar order at same price, but...

Do you work for IB? If no, do you receive money from them? Where is the help that IB gave in this thread? Trying to shut a poor but intelligent soul who did his homework and defend his case. Many reached a conclusion that his case is solid. What do you have to say to that Mr. ignonant...

Good! Defend yourself!

The guy who posted is a man, and you come here and try to appear smart by try to lower him. You are an idiot. Get lost. A customer should pay Zero commission! That is right Zero commission! That day will come. In case you do not know, liquidity has a premium, and the retail customer may one...

Look. You got to my nerves. I read your f*king answers as well as the answer of others. You come here and try to defend something that should not be defended. You make money on the back of the customers in many ways: 1. Timber hill 2. Exchanges 3. Other market makers/etc You fill orders...

A friend of mine is visiting with me, and responded on mybehalf to have fun/etc... He thinks trading is easy, and I challenged him to try. Hopefully the market will have a newbie/student. Joe's posts are great (funny and true)!

Why you did not discuss it then?

The bottom line is that trading is the most difficult profession to be profitable in, but if you make it you can make it big. Time and effort does NOT count. All what count is the return. Now give people some tips to succeed. I will start with this. p(t) is the price at time t. The right...

There are typos. Here is one: UNvention instead of Invention in "Therefore I am displeased to UNtroduce my latest unvention"
