Thanks, George I'm not talking about multi-threading or multiple vendors, and I probably didn't express myself correctly. I suspect neither AmiBroker nor any other platform vendor is set up to provide what I'm looking for. Thanks for the info.
Then why don't you tell more precisely what you are looking for instead of keeping yourself in the dark about platform vendors? Again ask their support and you will get a technical correct reply and probably any assumption will be gone.
TS has a newer "Portfolio Maestro" which is still not 100% reliable. TS is also 32-bit and mostly single-core. TS is working to improve. However, they are still behind both MC and AB in many ways.
TradeSim - Is it a competing KING?? From their website, where they explain why Amibroker implements positionscore variable and why it is a bad way to tackle the problem of selection http://www.compuvision.com.au/Examples/PortofolioOptimizationMyth.htm Interesting example from their website (check especially part 2) http://www.compuvision.com.au/Examples/HolyGrailPart1.htm
AB rules. I wish their support would be more willing to take on consulting work since the system can do so much and unless you are willing to spend time and $ using external consultants to learn its funtionalities, you can only scrape a portion of its amazing flexibility.I've use Sierra, TS, Investor RT, and scripting language in Esignal and TOSwim. AB is by far ahead when it comes to tech analysis. Case in point... With Excel to price out various option scenarios, trader can use AB to figure out questions such as... how much $ will I make or lose if I buy a call butterfly or a vertical spread IF I put on options position daily at 10am or if price > 5 day mvg average....etc. Those things can't be done with the other systems....
