comment Looking for C# library that provides/contains performance analytics
@DirkEddelbuettel, nobody disputed that a package for R exists and I acknowledge your expertise on the R side (among most likely other, to me unknown, areas) . But I think I made clear that I look for a C# library, not an R package. I am a bit irritated why the condescending tone, if you do not know of such library or dislike Windows or .Net for that matter, why having to comment?

comment What does “true”volatility mean in volatility comparison?
Do you have backup for this claim? I am not aware that institutional vol traders peruse specific compressed bar data to calculate realized vol. Some may, but to my knowledge there is no best practices that refer in any way to 5 minute data.

comment Looking for C# library that provides/contains performance analytics
@Joshua Ulrich, I am familiar with the library and have coded against it but at this point I rather like to perform all computations natively in C# or else export the dataset (most likely through Redis) and run the analytics in R. At the moment I prefer to run within C# only. R.NET is good at running a couple commands but shipping larger datasets through the API seems very slow.

comment What should I put on a math finance cheat sheet?
(1) Beware of model risk, (2) beware of model risk, (3) beware of model risk. If you always keep this in mind you will do just fine. If someone wakes you up at 3 in the morning and tells you that the trading performance deviated from expected model performance by metric x then you should immediately be able to answer the question whether the model should be retired/improved/reworked. I am telling you because it is not what might happen but what will happen.

comment What kind of return can an average algorithmic trading firm achieve today?
I pointed out it is possible but unless you are one of the top high frequency houses (with Sharpe ratios north of 7-10, translating approximately into a single day of losses in like 5 years) achieving 100% returns off the back of alpha generated (and not pure luck) is nearly impossible, especially not on "millions of dollars".

comment Free database for storing intraday tick data and querying bar (candle) data on budget hardware
@Nurettin, I do not think you get around the delay using any sort of SQL technology. SQL was not built to handle tick based data nor time series in general particularly well. You should look at column-based databases, do a search on this site there are several sections that deal with this issue

comment a good book on option pricing from theoretical and practical aspect
I disagree that this is a duplicate, OP specifically asked for books that highlight the practical aspect. I would recommend Taleb's "Dynamic Hedging", imho THE best book on options valuation and trading.
