Hi Roscoe,
THE GOOD:
I do have code to build continuous contracts. The basic design is that you provide a set of roll rules (encoded as text like 'roll_on_last_trading_day=-5') and a set of contracts into the algorithm, and it spits out a continuous contract as well as the list of rules that ...

Hi Dean,

I've used it a number of years ago. Excellent data content, very powerful, but my take is that programming skills are required to get the same level of backtesting ability that you get in trading blox.

When I worked with it, it has a menuing/scripting ability. This worked great in ...

I've recently (2003) worked for a couple turtles here in Chicago. One turtle used standard, absolute ...

Does anyone have any recommendations for .Net based numerical libraries that include statistics & probabilities, matrix algebra, ODE? I would have thought that there would be an abundance of such software, but not only are there seemingly few commercially available packages, there does not seem to ...
