LOL, ok, will try to fix it next time then.

Do you really believe that Bitcoin will grow to the level where it's market cap will be larger than the economy of Japan? At $300k, BTC market cap will be around $6T. I can hardly see this happening unless there is a big devaluation in the USD. $6T is slightly more than 15% of the total US...

Machines are always supervised by humans while they trade. No sane firm will leave the machines trading by their own without having humans monitoring their activities and ready to intervene if anything went wrong.

Of course it will always be like this. If the $1 call is priced at more than $1 (While the underlying is trading at $1) it will create a risk-free arbitrage situation, for example if the $1 call happens to be priced in the market for $1.3, anyone would simply buy the underlying at $1 and write...

Well, the SPY doesn't trade 24 hrs like the ES futures (Actually ES trades slightly less than 24hrs) The SPY options also doesn't trade 24 hrs, so short SPY options (calls or puts) are prone to gaps in SPY (Which theoretically are not there in the ES futures). Secondly, the SPY is the vehicle...

For the title, the deal reached is $900B not $900m, huge difference. Secondly, this is below market expectations of a $2+ Trillion, don't expect markets to rally a lot and even if they did, I think they will attract heavy selling pressure.

Practically, what are the risks of Bitcoin or other Cryptocurrencies? 1. Government ban --> Difficult to happen (Especially after legally having future contracts traded and other linked securities, both live and in the making). It's also very difficult or even impossible to have a consensus &...

Here is a small gift to everyone here interested in playing the vol short medium curve (Through any instrument). The file attached calculates the constant 30-Days Synthetic Futures (Between F1 and F2 of VIX futures) as well as the percentage of contango/backwardation at the moment. Your inputs...

Well, I actually meant 70%/30% weights in the decision making process, i.e. more importance to Delta to Premium vs. Theta (Instead of 50/50 or trying to choose something in the middle ground), that's all.

I would say that you need to strike a balance between Delta to Premium vs. theta in the framework you mentioned in the OP across different expires, typically between 1 day to 14 days. ATM options would typically give you the best delta for scalping, the choice of which expiry would largely...

SIL is the Comex Silver mini contract (1,000 Troy oz vs. the standard 5,000 Troy oz), so the margin is one fifth the standard (Only at $3.7K maint.) @IB.

In every business or commercial relationship, be it B2C or B2B, documenting activities (And especially communication) is a must, either for internal, external or regulatory purposes. Regardless of the medium of communication, be it mail/post/email/phone calls, even chat transcripts (Bloomberg...

Believe it or not, a lot of people here are taking what you are saying with more consideration, otherwise, they would have never bothered to respond in the first place. An exchange is where the actual trade happens between 2 parties or their respective agents (In the case of securities...

How can RH possibly be an exchange?? Can you buy and sell stocks on RH on a Saturday or Sunday (Where the actual exchanges are closed?) Let's suppose that on a Tuesday, NYSE had a technical problem and it went offline (Just a hypothetical assumption), can you still trade IBM or GE or JPM for...

A bit inaccurate metaphor. The structure between Crypto market and the regulated securities market is totally different. When a Crypto exchange is hacked, it means that both the Broker & the Custodian has been hacked. In the RH case, certain customer accounts were hacked, where hackers got...

This is true, most banks/companies who has a large retail client base has been slowly automating their customer service & support by using IVRs & other digital/online channels and adding tons of automated options in order to reduce customer service Reps. headcounts & thus reduce Opex. Welcome...

Interesting. Raising taxes on the rich (Or high earners) is as a sound idea as it can be, but the devil is always in the details. You must close tax loopholes. The wealthy & high earners can easily afford top class tax advice to legally evade or defer taxes, so the real beneficiaries would be...

Doesn't that page mention that SPX, OEX and VIX options are the only ones available or am I missing something?

It can be fetched from the IB API, but you will run into limitations for sure + you won't have access to expired chains anyway. www.cboe.com & www.historicaloptionsdata.com don't provide intraday historical data (Only EOD for options). www.orats.com, no tick by tick, they only offer a 2-minute...

You will not find this easily or cheaply, don't waste your time unless you are planning to trade at least a $50M portfolio in options and you want to test strategies before you commit this amount to it. This is not just institutional grade historical data, this is a niche Quant grade historical...
