comment VSTOXX Implied Volatility Calculation
There is nothing up to interpretation or choice about VSTOXX. It follows a very well defined methodology. What do you mean with "you experimented" with ...?

comment What is the difference between the Interactive Brokers demo account and a personal paper trader account?
I would not call the sampled data coming from IB inaccurate. It surely does not reflect a complete market as IB does not target high or ultra high frequency trading strategies with its API. But the prices are accurate and especially at times, when many assets print 5-10 times as many trades and most data feeds start to have a hard time to catch up, IB's feed looks pretty stable. Of course I am not talking about the top of the cream feeds worth several thousand dollars a month, but that is not IB's league anyway. I think IB targets buy side discretionary and retail.

comment Good criteria to sort state-space $\beta_{t}$ according to Kalman filter output
well, what have you tried so far in R re your real question, result ranking? (Re earlier messages, do not get me wrong please, I do like your question and +1, just wanted to clarify...)

comment Good criteria to sort state-space $\beta_{t}$ according to Kalman filter output
Ok, I get that but that is not related in any way to Kalman filters (other than that the prior algorithm involved a Kalman filter), correct? I was just confused because you spend 90% of your question on data acquisition and Kalman filter but your real question seems to be one of how to rank results. But maybe that is just my wrong impression

I am not exactly clear what your question is, do you mind rephrasing it a little or expanding on it? Thanks

thanks for explaining. Well, I can certainly add my take and references, though it will not be from a corporate finance practitioner's perspective.

comment Industry convention to track trading performance against market indices?
a) because what if you deposited 200 throughout the year (and had in no way accounted for that) then you would not have generated a return 20% but of 0%. b) What if your fund rose 20% but with a maximum drawdown of 50% and wild swings while the Dow returns were very steady with low variations? A case can be made that some may prefer to invest in the Dow even though it yields less. Can you imagine that there are people who are offered but reject to play a game to either win 1 mln USD with a probability of 99% or lose their lives with 1% probability? You need to build risk into your equation.

comment How popular is the IRR as a tool for capital budgeting, nowadays?
I used hurdle rate in a very loose manner, sorry for the confusion. If there are otherwise no other required rates then an example of "hurdle rate" would be 0%, meaning, the project is expected to be net profitable. But then as mentioned I have ever worked in corporate finance and so please excuse my incorrect usage of terminology.

comment How popular is the IRR as a tool for capital budgeting, nowadays?
Without knowing for sure I would reckon that IRR is still used in one form or the other because in the end IRR really just measures some kind of "hurdle rate" and the question becomes is this a return that overcomes the cost of funding, the required return, a competing return. In the end that is what most everyone is concerned about whether it be personal finance, trading, funding, capital budgeting. But it is just a hunch and definitely does not qualify as answer so maybe someone with direct knowledge can add more value...

comment Industry convention to track trading performance against market indices?
Unless I have overlooked something no assumption was made how the closing account balance reflects deposits and withdrawals and thus I made the assumption that it was adjusted higher by deposits and lower by withdrawals and that d/w are made post trading each day. Will edit to be more specific about the assumptions. Thanks for pointing out.
