Hellp I found it is very slow with my ATS. I want to add more Ram on my computer, but if Sterling only support 32-bit, it is useless for the Ram higher than 1G. Does Sterling TraderPro support 64-bit or 32-bit only? Is SterlingTraderPro bale to support 4G memory Ram? Thanks so much for your reply!!
Do you mean the API feed? How many quotes per second are you receiving? I doubt having more RAM will help. What language is your ATS written in?
Thanks for the reply!! I am sorry I don't know how many quotes per second I receive, but in my target stock pool, there are around 500 stocks in the list. It is slow to receive the data when I run my program. If the Sterling only supports 32 bit, I can't install 64 bit Windows XP, which means my RAM will be used no more than 3G. I asked someone to write my ATS in VB and .net.
I just received the reply from Sterling, Sterling Trader Pro will run in 32-bit mode on the 64-bit Windows OS. Sterling will use the /System32 folder and not the /System64 folder. There is no 64-bit version of Sterling. Sterling Trader Pro, and any other 32-bit application, can only make use of up to 2 GB of RAM, as an individual app. But if your computer has 4GB of RAM, that is all the better; Sterling can use up to 2 GB, and some other application(s) can use the other 2 GB.
500 stocks will definitely slow you down. Sterling quote server isn't what it used to be my friend. Try having a few level2 windows open with that. You'll definitely feel the freeze. When you say " It is slow to receive the data when I run my program.", do you mean your ATS, or Sterling? Although this may just be me, I wrote an ATS in C#.NET and it gets quotes very slowly, only up to 500 per second. Thats enough to look at maybe 25-50 stocks without lag. Whereas, I wrote another ATS in VB6.0 and it gets quotes at over 4000 quotes/sec. Coincidently, their ActiveX examples are mostly written in VB6. The ones written using .NET don't download quotes, they only monitor open orders. Have your programmer add a quote per second counter in your program But if your programmer can get past that quote problem, please give me his contact! .
