Shifting sands: March 2015
http://petewerner.blogspot.com/2015_03_01_archive.html
A man with a hammer. Tuesday, March 24, 2015. Simulation and relative performance. There’s been some nice posts on randomness the last week or so, in particular here. I would like to look at how we can use simulations to get a better understanding of how some aspect of a trading system holds up relative to a bunch of random trades. In this example, I look at entries on weekly data for SPY. The entry signal is to buy if the previous week closed down. It looks like this. We can see there’s not a lot ...
Rcpp: Seamless R and C++ Integration
http://dirk.eddelbuettel.com/code/rcpp.html
The Rcpp package provides C classes that greatly facilitate interfacing C or C code in R packages using the. Interface provided by R. Rcpp provides matching C classes for a large number of basic R data types. Hence, a package author can keep his data in normal R data structures without having to worry about translation or transfering to C . At the same time, the data structures can be accessed as easily at the C level, and used in the normal manner. Transfer from R to C , and from C to R. Starting with r...
