Open source C++ gnuplot videos for charting is very impressive

Open source C++ gnuplot videos for charting is really impressive

 

The first C++ project that I have looked at is gnuplot which is open-source meaning free. I have looked at various videos online to see the capabilities of this library. Personally, I’m quite impressed considering it is open source. I have also verified that I got it working on my own Ubuntu Linux environment so check out the videos here.

New Excel script to instantly use this Portfolio Optimization tool

I’m currently prepping a 30 minute video tutorial on how to use this crucial portfolio optimization tool I found from Matlab.   I have also included a script that will automatically down load any chosen Yahoo finance symbol with the proper sizing for an Excel spreadsheet. I will be releasing this package with all source code and the video Tutorial over the next day. I will post as a very limited time as a flash sale. This is already available for my Quant Elite members. You can also get a preview of this new script which will get you instant portfolio asset weightings you should use to get optimal returns with expect drawdowns and volatility. Check this impressive package video out here.
