BRO. Basic computer rules: The faster the CPU(Ionly use Intel) the better. The more RAM the better. The better video card the better. Solid state hard drive - better
I trade on a i7-4930K @ 3.40GHz. and a 4 -monitor video card. Basically a gaming computer that I bought as a package from https://eztradingcomputers.net/.

I have used NJT for a long time as I have a life-time license. It has its issues but nothing to do with the hardware.

IMHO


^^ This.


If you are trading, you should have no problem dropping 1.5 G's on a good machine. Buy the CPU just behind the front of the curve. That is an AMD Ryzen 7 3700X. No reason to go with intel whatsoever, unless you like their logo.


RAM - 32GB minimum.
SSD - 512GB, and another 2TB if you want to record sessions. Magnetic disks have no place in modern computers, forget about it.
Video card - same as CPU, get something just behind the curve. GeForce RTX 2070 for example. If you do this, you can record 4k or 2 1080p screens, with almost no CPU, which is ideal for trading

Generally agree but with some platforms being cloud based now, desktop performance may be less important than it was.

Best value for money TODAY I agree. Of course buying a top end chip might add years to your replacement time frame.

Strong words. Any supporting logic behind such a statement?

SSD's are much faster but in my personal experience have a higher failure rate the HDDs. So if you can afford it Dual SSDs in RAID 1 adds more protection .. but you still need to backup!

They are much slower but in most cases you can recover all your date from a failed HDD but you can not recover anything from a failed SSD. So safety vs speed may be a better discussion trade off, especially in high volume low speed requirements (like photots) than a blanket never!

For example, see https://www.cpubenchmark.net/compare/AMD-Ryzen-9-3950X-vs-AMD-Ryzen-9-3900X/3598vs3493

$750 vs $420, with very similar benchmarks. That $750 chip will depreciate much more quickly, and if you didn't know what was in the machine, in day-to-day usage, you wouldn't be able to tell the difference, for most use cases.

Must personal experience, having run Intel for the past 20 years and switched to AMD 5 years ago -- for two similarly-classed, similarly priced chips from AMD and Intel, the AMD will generally have a bit beefier specs, or will be a bit cheaper, given similar specs. Plus, there's no spectre or meltdown Basically, look at some benchmarks, and if you find an exception to this, I'd be interested to see it.

That's a good point -- however, modern SSDs are very reliable, and are in some ways more reliable than a mechanical drive. Reliability and error metrics vary greatly depending on the working set of the system. For trading applications, SSDs should be quite reliable as systems write data, but not loads of it (whereas a security system which writes 24/7 to a drive would be better suited with an HDD).

Just saw this thread and so I thought I might pick your brains about an issue I am having. Bought a "decent" computer that has been great but lately during "high data" times like the Open it literally can't keep up. Not sure what could be the issue as it didn't do this the first year. I have tons of storage left...only 16 GB ram but it's been fine...i7-6700.

Anyone had similar issues? Thoughts?

Thanks for any help...

@Blue Eagle, perhaps this could help...

https://ninjatraderecosystem.com/user-app-share-download/set-process-priority-to-high-giving-it-preference-over-other-applications-that-are-running-2/

Updated: Oct 21, 2015 5:55AM ‐ New Priority value of BelowNormal. New parm Show NT Priority. Priority now also checked/set in State.Terminated.
Updated: Oct 16, 2015 9:50PM File ‐ Priority changed only when required.
Updated: Oct 16, 2015 10:50AM File & Text ‐ Converted from NT 7. New parameter Debug message to Output Window.
Author: James R. Walker
All the applications running on your computer equally share your computer's resources. The NinjaTrader application runs at Normal Priority with all the other applications. Especially during fast markets, when other applications are running on your computer, NT is not processing incoming data as quickly as your computer would allow and possibly losing trade data from your market data service. By default, this Indicator sets NinjaTrader's Process Priority to High, giving it preference over other applications that are running.
This Indicator allows you to set NT's Process Priority to one of four values: High, Above Normal, Normal, or BelowNormal. You may want to use High during your trading day and Normal at other times. You could also set it to BelowNormal to do backtesting in the background while you use your computer for other tasks.
Adding this Indicator to one chart in your Workspace will set NinjaTrader's Process Priority until you exit NT. The Indicator will check before setting the Priority and do nothing if Priority is already set to the Priority specified in its parameter.

Edit, footnote to more by him if interested (I saved this comment from a 2015 post by him, no idea if still applicable): "Current status of all my shared Indicators is available at https://forum.ninjatrader.com/sh ... hp?t=71963 .

There are many variables. The likely culprits are, in order of likelihood IMO:

- problems with your data feed itself delivering the data to you -- this is not uncommon in super high traffic situations like recently
- problems with your internet connection (your ISP, your wiring, your router, your WiFi channel) -- i once had a problem with latency and it was an issue with the physical cable outside my house!
- your trading software is not handling the incoming data well -- that is, it's not efficient enough at handling the data as it comes in
- your system resources are being used by other running applications -- "storage" as you say has little to do with performance issues; check your running processes and ensure nothing is high on CPU, and ensure you have a decent amount of free RAM

I don't know what you mean by 'decent' and if you bought it stock or created it yourself. For me, I quickly realized the best way is to pick your parts. I love Microcenter...they aren't all over, but if even remotely driving distance, they are worth the trip. Otherwise, I think you can do it online or go to Tiger Direct. In any case, it's not that hard to change out parts or upgrade them yourself. You just have to make sure you get something compatible with your motherboard and software (which is where Microcenter shines, b/c you can have them look up your system and they will point you at what will work). When I do a new computer, I go there, talk through what I need, take their reco'd list of parts and go home and look up their specs and reviews. Then I go back with what I want they build it for $139.

Also do a speedtest.net and check your connection. I will say that cable is the absolute worst. They have literally thousands of homes on one node and when everyone is online, speeds and crimp to nothing. I have literally found a slower DSL to be more stable! That said, fiber is the best...rarely have issues. I also try to hard-wire the computer to the router, but if that's not possible, you can also get / have the internet provider put in a repeater right by your trading desk to boost the signal and, if desired, hard wire to the repeater. I'm getting 200 mbps up and down so I've had no issues with data in this volatility.

Question not so much about CPU or computer build itself but should I have an antivirus|malware|internet security application on my trading PC?
