Nate - I wanted to thank you for your sharing of your collection of trading based technical indicators.
I wanted to share similar work with you and your followers in the hopes that some may find it complimentary and useful. As it isn't a file submission direct to Mathworks I really can't create my own thread.
I have created a C++ mex-able wrapper for the open source TA-LIB library of functions.
It is available in the repository of http://www.openAlgo.org
Thank you for this collection. On a cursory read of the code, if I am correct there is an issue with the logic employed in tradeSignal if I have understood it correctly. Specifically, the input 'ind' and logical 'AND'. As I understand it, 'ind' is normalized such that 0 = sell, 0.5 = "skip", 1 = buy. If you logically AND 0 & 1 (sell and buy) the result is a 0 (sell) however this is not the desired result. I'm posting this in the spirit of others trying to review this code and welcome any correction on my understanding.
