LMAO. Think of it as an investment. It's not like the debit is gone forever...you can always cash in whenever you want!

I'm fairly sure they do, not sure which part cdowis is referring to. E-mail: tpreston@thinkorswim.com MoMoney

Not sure there is a closed-form analytical solution for POT. However, take your pick of numerical methods: lattice models e.g. binomial, trinomial etc. You can choose to assume the brownian motion stochastics for stock prices. Or...just use ToS like everyone else :) MoMoney.

Despite your near incessant and perpetual expressions of incredulity over why the market is going up over the last few days, kudos on making this call! :) It's up there with your 06/08/06 call: http://www.elitetrader.com/vb/showthread.php?s=&threadid=70638

Do you believe your options are priced on TA,S/R or on volatility -> probability?

Thank you for the excellent synopsis. I will be giving it a miss! Agree on Vidyamurthy's volume. I think even those without quantitative or scientific backgrounds can glean some useful information with perseverance but you're right about the target audience. MoMoney.

Good to know. Care to cite any reasons? What is your take on Vidjamurthy's Pairs Trading so that I can calibrate my opinion with yours. MoMoney.

thinkorswim have done a few seminars on the top of pairs trading with options e.g.: http://mediaserver.thinkorswim.com/transcripts/June_21_2006_pairs_trading.pdf Though I believe option positions are used for limited risk purposes rather than leverage. The last thread that attempted to...

It doesn't sound like you intend to gamma scalp systematically. Rather, day trade discretionary with long straddle as "backup". There are some flaws to your plan. Have a look at this old journal. Suggest read all of it right to the end for some possible insights...

For more modest needs (and more modest prices) you may prefer one of the foldable Sunlinq products: http://www.globalsolar.com/consumer.htm Usually can find on E-bay. MoMoney.

Have you tried the cancel/replace technique? I've outsourced the task of cancel/replace to an enterprising company situated in a third-world country. I effectively now have a whole room of people available 24/7 hitting cancel/replace on my orders all day long taking advantage of the no...

This may not be the case depending on the technology. For example, when you place a trade there could be technology to notify their black box such that the black box then mirrors the trade i.e. No strategy needs to be revealed it's simply a matter of mimicking after the fact. I'm sure the OP...

Alas, no free trade if I understand you correctly. Entering diagonals based on getting a credit/minimizing debit is potentially a dangerous exercise if not looked at in the context of the other variables IMHO. One can think of diagonals as a reduced cost calendar spreads. What reduces...

Yes, plus there are plenty of places to take Spanish speaking classes.

Let's not forget www.tradeking.com: $4.95 per trade + $0.65/contract.

There may be some confusion here. SPAN is a risk-based margin system. SPAN risk-arrays are calculated by the exchange e.g. CME, Euronext.LIFFE, SGX - they all use versions of SPAN risk-based margining. They also provide desktop software e.g. PC-SPAN so that you can decipher the risk-arrays that...

Good luck. Each day that goes by there is more pressure to lower commissions across the industry IMO. If you have a decent trading history with them your chances may be good. I know they have gone down to $1.00/contract no ticket charge for some people.

Last time I checked, the answer is no. They will not price match anyone. To paraphrase one of the co-founders: "We are not competing with IB" Bear in mind that IB has cancellation fees (though there are credits to offset) Other brokers like Optionsxpress etc. are fair game for price...

Negotiate. Make your case. Regardless of broker. Listed rates are as follows: http://www.interactivebrokers.com/en/accounts/fees/commissionStockIndexOptions.php?ib_entity=us >10,000 contracts/month $0.50/contract. Trading teenies: $0.50/contract or $0.25/contract. If you're...
