NT for Linux ... ?

[canuckbucks]

Have to give 2 cents - regardless post is halfa' decade old...Please accept my confession of guilt and forgive my assumptions and unrealistic expectations. I got ahead of myself assuming NT7 stability issues would be at least partially resolved five years later. My bad.

*sigh*

I have NT crash mainly when I'm debugging a strategy in Visual Studio, but not during the day when I leave it and let my strategies run. How much stuff do you have running on it? I have about 10 charts and strategies running. I limit it because I know it can't handle too many threads. The problem appears to be when a thread is delayed for too long, then the system hangs. It is really annoying during debug because that is all you are trying to do and it hangs. But good luck waiting for a linux version of NT. I played with some free packages on linux but was discouraged.

Well, you have gotten your braking points in Visual Studio, right? I never run more than 6 charts plus my strategy, for which i know it's a resource hog, because of heavy calculations on 27 currency pairs, although, I'm trying to optimize the code.
But, I'm getting the same freezing moments even when I'm not running my strategy, for example when I'm running weekly backup.
And I'm not waiting for linux edition, unfortunately I know it will never happen

Word. Just think of the tech evolved trader you could corner the market on as one of the very few Linux trading platforms.

Winblows.

Yep, a picture is worth a thousand words... One of the many Oopsies during the day LOL
But it's NOT funny, I was thinking to build a "supercomputer" LOL something with at least 8 cores processor min 32GB ram fastest SSD in Raid 0 , but nah, it won't solve the problem... THE PROBLEM IS WINBLOWZZZZZZ!!!!!
Some people shoulda understand this!

I think by porting to native Linux you would solve the BIGGEST disadvantage of NT7 - constant crashes. It is shame that I need to babysit a 1000$ software on WIN7 running on a Quad Core processor with 10GB ram and SSD drive!!!

Linux & NT

Unfortunately this would not be supported. NinjaTrader requires the .net framework to run which is a windows component, which means that NinjaTrader requires windows. There is no change to this at this time moving forward.

Any news about NT and linux ?

The main interest I think is to have NT+broker API hosted, so no power or network failure ...

Thanks

bump. I have about had it with windoze crashes with NT7. If it isn't the API, it is the historical data, or NT7 just freezing (3 times tonight already) forcing a hard kill.

I've tried every method possible to run under Linux, it's just not worth the hassle. Spend the dollars on a specific windows 7 trading box. Never looked back.

Thanks guys for your thoughts. Just started testing NT and my enthusiasm for it is somewhat diminished by my irritation about having to use Windows again. I'll try the various methods of running NT under Linux and might just go for the "buying a Windows trading box" option if it's not satisfactory.

But seriously, the Mac and Linux communities are only growing and if you're a company trying to sell a product (a very good one btw), then reaching out for those user groups is maybe not so far from interesting. Just a thought..

Oh and I forgot to mention that I've used Tradestation for years on Linux using VMware and I will not go back in that direction. It works for small time traders but not for significant volume and sophisticated algorithms. It is just too slow for professional use.

I don't think NT developers or management have any metrics on how many people trade on Linux. I will only buy NT when Linux is supported. How many other people exist like myself?

NT in VM under Linux

I shall appreciate it, if you will share your Ubuntu experience and setup with me.

I am testing NT on Slackware Linux under VirtualBox with XP. So far it works flawlessly.

XP is stripped down (remove all unused services and eye candy). It is fast and stable on the VB emulated hardware (i.e., it runs 24/7 for weeks without crashing). Only used for trading software so no antivirus software needed, it is behind my stateful Linux firewall and the XP firewall.

Windows OSes have had trouble with multitasking from the get go so the fewer programs you have running under XP the faster and more stable it is.

If you have a modern CPU with hardware virtualization, the performance difference between VM and native hardware is negligible (much less that the performance difference between a low end and high end computer).

I have 8GB ram on my computer and I assign 3GB to VM.

XP running in the Linux VM is faster than Vista on my laptop (it has only 2GB ram).

Treggs,

If you are that concerned about the difference between the VM and native boot (maybe 5% difference?, others can tell you exactly what you give up, but I would guesstimate (snigglet) about 5% on the high end).

NT is free for testing. Setup old boxes to burn systems for you. It's cheaper and less time consuming than trying to get a square peg in a round hole.

Think "appliance". Software+Hardware = appliance. You want back testing appliances. This isn't about trying to make your life pretty and cozy and fit it all in your nice pretty mac. It's about utility and function. Computers are free and NT is free. When PCs that are 1 generation old can be procured on ebay for dirt cheap, it makes no sense to worry about getting things to run on different platforms. Are you also trying to get a microwave that is also your television and your refrigerator?

Seriously guys, I'm a HUGE linux advocate, but this is not about Linux. It's about TRADING, and whatever "appliance" you can find to do the job, you use and you build your platform around the appliance. There is no advantage for NT to go to Linux. As much as I would like it, it doesn't serve their market. You wouldn't go to GE and ask them to make your microwave fit in your refrigerator because you want it nice and neat and you don't like having two seperate power supplies.

They will tell you to simply put the Microwave on top of the refrigerator and stop emailing them with your suggetion ;-)

For those running virtual machines on a mac, wouldn't it be better to run windows natively using bootcamp? Then you could use all your machines resources to run NT which is a definite advantage if you are backtesting.

I understand the appeal of a virtual machine being moved between machines but the same can be managed using the NT backup feature.
