I plan to buy a second laptop soon. I was wondering if there would be a memory limit beyond which Ninja won't find any use.
I was planning to buy 3gb but I could add up to 6gb. To your knowledge, what is recommended for backtesting/programming/trading ?
Can you help answer these questions from other members on NexusFi?
i am not shure but i think i remember something with : "NT 7 + Win 32bit is still limited to 1,5 GB-RAM-usage"
that i remeber from a webinar for NT7 - but not 100% shure - maybew someone can confirm this.
so this would mean only 64Bit stuff will make more RAM-usage possible for NT7 .
but also its clear that NT7 will not uses that much RAM as NT6,5 did and will ahndle RAM much smarter - cause NT6,5 was a bit "out of control" in its RAM-handling.
so even if NT7 32 bit is limited to 1,5 GB-RAM it will need much less than this i think.
so your decision will be related to the OS you plan to use.
Go for 6GB if you can and if that's your hardware limit. Run Win7 Pro, and you get a a free XP VM from Microsoft you can run in background. You can assign it 2-3 Gigs of RAM, let it do backtests and things while you develop on the main installation. That basically alows you TWO NT installations on one machine.
Both NT7 32-bit and NT7 64-bit have been optimized greatly over NT65 in terms of memory usage, it is likely to not be a real problem. I tested NT7 32-bit in early betas and was able to optimize two years of tick data without running out of memory. Still, the 64-bit version will give you more headroom, but keep in mind any DLL indicator versions, as well as some data feeds like Zen Fire, don't work in 64-bit without updates or in some cases not at all.
For ZF feed, which still 32-bit only, the idea is to:
- get the tick data using NT7 32-bit (a simple backtest)
- optimize the strategy using NT7 64-bit (it will use the data downloaded previously by the 32 bit version, no need to be connected then).
With the 64-bit version, and large backtests optimization, I saw NT7 64 using more than 7 Gb, and give some reliable results.
