My formal education is in economics. My programming skills and computer knowledge are self-taught. I have an uncanny ability to find answers to questions outside my immediate expertise. I have a deep love of learning and I enjoy building / fixing all kinds of things -- software, computer hardware, engines, etc.

comment How does Volatility Pairs Trading work?
If you got a sufficient answer elsewhere, you can either link to it in the comments, or answer the question yourself (but that can depend on the other forum's rules regarding who owns the content; you might be okay as long as you provide proper attribution to the original author of the answer).

comment How does Volatility Pairs Trading work?
Different forums have different opinions. I find cross-posting without disclosing to be rude. You're asking for people's time, but do not let them know to check other forums to see if there's already a satisfactory answer. The only reason I noticed your cross-posting is because I monitor several forums' RSS feeds.

comment Why would a 9% dividend payment halve the stock price?
If the company transfers a huge amount of their cash to their stock-holders, why would you expect the company value not to change?

comment where to find historical option prices?
Welcome to the site. No one will be able to tell you if Bloomberg data is "enough/reliable" unless you provide more details about what you actually want to do with the data.

Who is the data provider? Doesn't their metadata indicate the differences between the series?

comment How is PnL calculated
Welcome to quant.SE. Unfortunately, your question is both too basic and too broad for this site. You question would be more on-topic if it summarized what you already understand about the calculations and asked a specific question about the unclear part(s).

comment ETFs have lower tracking error than Futures?
1) isn't the ETF error larger (0.0012959 > 0.0006794)? 2) I would expect the ETF tracking error to be lower. It holds the actual index components and has fewer transactions than the futures index. The futures contracts must be rolled periodically, while the ETF only needs to transact for index constituent changes.

comment How to construct a deterministic trading model based on a loess (local regression) model?
Sounds like you have a hammer and are searching for a nail. The data should inform the model choice. It's a mistake to choose a model and then search for data to apply it to, because "all models are wrong".

comment Isn't a perfect economic system always in debt?
This question appears to be off-topic because it is about economics, and is too broad.

comment Implementing A 50/50 Prediction Model Strategy
A model that's right <50% of the time can be profitable. Many trend-following trading systems are only right 20-40% of the time, but are profitable because the winning trades are so much larger than the losing trades.

comment Is the market really Normal. Is Implied Volatility Historically Correct?
It's still wrong. 10.99*sqrt(20/250)*195.6 = 608. 195 +/- 608 != 201/189.

comment The option values are different from two r package - foptions,rquantlib
Yes, it's in Fortran. You could compare the current version with archived versions of fOptions on CRAN. Maybe one of the older versions had a pure-R implementation.

The source code for both is available. Have you looked at it?

...and how does 195+/-608 give you 233/177? Even if it did give you 233/177, don't you see a problem with your 1-month standard-deviation band being ~3x larger than the annual VIX?

I see a lot of statements. What's your question?
