comment Fractals indicator (Bill Williams) R Quantstrat
Please don't cross-post. At minimum, tell people you're doing it so they don't possibly expend their valuable effort trying to answer a question that was answered on another forum they do not follow.

comment Does anyone know where I can find a free efficient frontier tool, or an informative and legitamate/academic graph of the efficient frontier?
I second Kyle's recommendation against. It has some interesting and valuable concepts, but the implementation is shaky.

comment R TTR/RSI does not behave like a Bloomberg RSI
Of course that's not close! If you use a different moving average, why would you expect the results to be the same? I said the default should be close.

The default should be close, except for the issue I mentioned in my previous comment.

comment R TTR/RSI does not behave like a Bloomberg RSI
SMA is not the "sum of gains over last x days"; it's the mean. I don't understand why you're confused that the results are different when you specify a different moving average. I would be concerned if they were the same. The potential bug I referred to is that the positive/negative values are set to zero (instead of missing) when calculating the down/up averages, respectively.

I need to investigate more, but it looks like this may be a bug in TTR::RSI.

Answers should contain enough information to actually answer the question. A simple link to another site should just be a comment.

How do you plan to generate data through the high and low price when you don't know the point in time at which those prices occurred?

This question appears to be off-topic because it is about macroeconomics, not mathematical/computational finance

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.
