Build the Best Stock Trading Computer – Guide for 2018

If you’re looking to purchase a new computer for day trading, picking out the components you need is the first step. We’ll eliminate the confusion with this awesome guide!
By Craig Johnson - June 8, 2017

In the guide, we’ll walk you through step by step to help you pick out the best components that go in a trading computer. Computer technology changes rapidly, if you are reading another article written a year ago (or longer) then the information is outdated. This guide is for components going into 2018 and we’ll keep it updated as components change over time.


Blue Aura Trading Computers


If you need to save a small amount you can attempt to build the system yourself. If that’s the route you want to go, we’ll show you exactly what components to buy. Many people though don’t want to hassle with trying to build, test and troubleshoot a new computer, if you fall into this category then we can help! It doesn’t have to cost a lot to buy a trading computer professionally built from a company like ours. We started Blue Aura Computers over a decade ago to help traders purchase the best trading computers possible at the lowest prices.

It’s important that you seek advice from professionals that have experience building, testing and configuring thousands of trading computers.

We’ve sold thousands of trading computers to customers for over a decade. Click here to see all the trading computer systems we offer.

Now, let’s get to the components!

Intel Processor


The answer to this is easy – every trading computer in 2018 should have an 8th generation Intel Core processor. Most of them are priced around $400 or less and are the fastest overall consumer desktop processors every made. The Core i7 chips have Hyper-Threading and Turbo Boost to give it a little extra speed when needed. If you’re on a tight budge, you could save another $100 or less and go with an Intel Core i5 8600K. My advice is that this is not an area to penny pinch, buy the 8700K if you can.

Top Six-Core Processors for 2018:

  • Intel Core i7 8700K 3.7GHz Six Core (4.7GHz Turbo Boost) – Intel Z370 Platform
  • Intel Core i7 8700 3.2GHz Six Core (4.6GHz Turbo Boost) – Intel Z370 Platform
  • Intel Core i5 8600K 3.6GHz Six Core (4.3GHz Turbo Boost) – Intel Z370 Platform

Top Quad-Core Processors for 2018:

  • Intel Core i7 7740X 4.3GHz Quad Core (4.5GHz Turbo Boost) – Intel X299 Platform
  • Intel Core i7 7700K 4.2GHz Quad Core (4.5GHz Turbo Boost) – Intel Z270 Platform

Also, Intel does sell a lineup of more expensive processors with 8 or more cores on the X299 platform, these are our Trader 9000 Series systems. The difference with these are the cores, they have 6, 8 and 10 cores. These processors are going to be much more expensive, and actually the core clock is a little bit slower on them, so you get more CPU cores but at a slower speed.

Top Processors for 2018 with 8 or more cores:

  • Intel Core i7 7820X 3.5GHz Eight Core (4.3GHz Turbo Boost)
  • Intel Core i9 7900X 3.3GHz Ten Core (4.3GHz Turbo Boost)

Our Current Top Pick for 2018

The best overall pick for speed, price and overall performance is the Intel Core i7 8700K. This processor is found in our Trader 8000 Series trading computers, specifically the Trader 8000 Elite model. The 8700K is 3.7GHz six core and goes up to 4.7GHz with Turbo Boost.

ASUS Motherboard


This section is right after the processor section because the processor you pick out will dictate what motherboard you need to get. The first thing I’d like to do is clear up a little confusion with motherboard sockets.

The socket is the place you put the processor on the motherboard. The type of socket has to match the processor. The socket type on our Trader 8000 Series trading computers is LGA 1151, or commonly referred to as simply socket 1151. LGA 2066 is the socket type for the more expensive processors listed above.

  • LGA 1151 = Intel 8700K, 8700, 8600K, 8400
  • LGA 2066 = Intel 7640X, 7740X, 7800X, 7820X, 7900X

So why is knowing the socket type so important? Because that will dictate what “Chipset” you get on the motherboard. This can seem a little confusing at first but basically if the chipset on the motherboard is compatible with the socket on your processor then you can use that motherboard. Of course, you want the newest chipset so you get the best performance with your processor.

There are really only 2 motherboard sizes to talk about: ATX – normal sized motherboard with more connectors onboard – more usb, hard drive sata connectors, video card slots, etc. MicroATX – much smaller than standard ATX. Usually only 2 video card slots, less usb ports and sata ports. We recommend buying a computer with a normal sized ATX motherboard, the MicroATX boards strip away too many board slots and other features.

Top Motherboards in 2018 for Socket 1151 (our Trader 8000 Series systems):

  • ASUS TUF Z370-Pro ATX

Top Motherboards in 2018 for Socket 2066 (our Trader 9000 Series systems):

  • ASUS TUF X299 Mark 2

Important – only use ASUS brand motherboards. Getting into all the details is beyond the scope of this guide. But brands like Gigabyte and MSI don’t work well in a trading computer, they have a buggy bios interface and have unpredictable unreliability. ASUS is the largest motherboard manufacturer in the world – they have the best designs and their boards provide the fastest performance for Intel chipsets and processors!

This doesn’t get discussed much in guides like this, but I’ve found that MicroATX boards have slightly lower performance with the same processor than the ATX equivalent. The ASUS TUF Z370-Pro motherboard uses the Intel Z370 chipset which performs slightly faster than other Intel chipsets on Micro-ATX motherboards with the same 8700K processor installed. The performance difference isn’t huge, but we have verified this with testing, usually less than 2% difference. It’s best to make sure your system has a full size motherboard to get the maximum performance out of your processor.



If you’ve owned a lot of computers in your life, you’re probably familiar with computer RAM. These are the sticks that get installed on the motherboard.

How much RAM do you need? I would say right now 16GB would be the minimum amount, if you are on a tight budget you can get by with 8GB but I wouldn’t personally go that low. If I were building a trading computer for myself today, I would get a 32GB kit – two 16gb sticks.

What brand of memory is best? Do not use Corsair memory! We have had such bad luck with Corsair sticks in the past that I can’t recommend that brand. The top brand has always been and always will be Kingston & Crucial. Their RAM is priced slightly (not much) higher than others but it is well worth it, it’s rock solid and rarely goes bad. We really love Crucial brand memory and have been using it for years.

Top Memory Kits for a Trading Computer in 2018:

  • 16GB DDR4 RAM 2133MHz or 2400MHz Crucial (two 8gb sticks)
  • 32GB DDR4 RAM 2133MHz or 2400MHz Crucial (two 16gb sticks)

You can install up to 64GB on our systems right now by using multiple 16GB sticks. We recommend going with a full 32GB kit, you won’t regret it!

Solid State Hard Drive

Hard Drive

The hard drive is where everything is stored – your operating system, files, music, etc…

There are 2 types of hard drives – mechanical and solid state. Mechanical drives offer more space for less cost, but are slower. Solid state hard drives (also known as SSDs) are more expensive per GB but are much, much faster.

In my opinion, speed is more important that size. Any trading computer built or purchased in 2018 should have an SSD drive as the primary boot drive. If you need additional storage, adding a 2nd hard drive to the system such as a 1TB Western Digital is common.

What brands are the best? Kingston and Samsung are the only 2 manufacturers we recommend. We don’t recommend Corsair SSDs. Kingston provides the best price/value and they are very dependable drives. Samsung is the current king of speed in the SSD market, and their drives are also known for very high reliability.

It’s also worth mentioning a new type of SSD called an M.2 SSD. It is a type of SSD that looks like a stick of RAM and is installed in a special slot on the motherboard. I really believe this is the future of SSD technology, but for now with the current state of the technology it is not the way to go. These drives tend to be way over priced and have some performance gaps that still need to be addressed. We do sell them in our trading computers and the top brand is Samsung for these drives.

Top Hard Drives for a Trading Computer in 2018:

  • 240GB Solid State Drive – Kingston V300 SSD SATA III
  • 250GB Solid State Drive – Samsung 850 EVO Series SSD SATA III (my personal favorite!)
  • 512GB Samsung 960 Pro PCI-E NVMe M.2 SSD

Video Card

Video Card

First off, you don’t need an expensive gaming card for a trading computer. There will be no benefit to using one and you’ll end up just wasting money.

Video cards plug into a certain type of slot on the motherboard. MicroATX boards will usually have 2 video card slots. ATX boards will have 3 or 4 slots depending on the chipset.

The MicroATX motherboard we recommended above has 2 video card slots, so you can install 1 or 2 video cards.

The socket 1151 board we recommend above has 3 video card slots. So you can install 1, 2 or 3 video cards.

The Socket 2011-v3 motherboard we recommended above has 4 video card slots. So you can install 1, 2, 3 or 4 video cards.

Top Video Cards for a Trading Computer in 2018:

  • 3 Monitor Support – 3x Digital Ports – 2x DVI, 1x HDMI (NVIDIA 710 GT one card)
  • 6 Monitor Support – 6x Digital Ports – 4x DVI, 2x HDMI (NVIDIA 710 GT two cards)
  • 12 Monitor Support – 12x Display Ports (NVIDIA Quadro P600 – three cards)
  • Our favorite is the NVIDIA GTX 1050 cards. They are more powerful gaming cards that support up to 3 monitors per card, so with 2 cards you can get 6 monitor support.

Only use the NVIDIA Quadro cards if you need 12 monitor support. They offer no performance benefits whatsoever other than the ability to support 4 displays on a single card. The NVIDIA workstation cards are not quieter and they do not perform any better than a standard lower cost NVIDIA desktop card.

DVI and HDMI are entirely interchangeable. They output the same digital signal and can be converted between each other with adapters so it doesn’t matter if the video card has DVI or HDMI – you can use a DVI or HDMI connector on the monitor with the right adapter.

The NVIDIA Quadro P600 comes with the adapters to convert the display port to DVI or HDMI – no need to buy anything extra with those cards!

The standard inputs on monitors is still DVI/HDMI so I wouldn’t get too caught up in needing a monitor or video card with display ports, plus if you do you’ll need to convert them anyway unless your monitors happen to have a display port.

Common Adapters & Cables

  • Mini-HDMI to full HDMI adapter (we include this adapter for free with all of our systems that have the 710 GT cards)
  • HDMI to DVI cable (converts from one to the other) – We sell 15 ft. cables that have dvi on one end and hdmi on the other end
  • DVI cable – We sell 15 ft. cables that have DVI on both ends

With the trading computers we sell to our customers we include all adapters needed to get you up and running!


There are a TON of cases on the market at any given time. There are more manufacturers than we care to list. Only 2 manufacturers are worth mentioning – Cooler Master and Fractal Design.

Cooler Master is by far the biggest name in computer cases. We’ve stuck with them for our custom computers because of their outstanding build quality. Cooler Master has thick steel so their cases don’t feel cheap or flimsy.

We’ve been using Fractal Design cases for about 3 years now. My favorite case of all time is the Fractal Design Arc Midi R2. It has removable fan filters, a front fan speed controller switch and it supports 140mm fans where most cases only support 120mm.

My favorite case by Cooler Master is the HAF 912 model. It is a more basic case, but has Cooler Master’s awesome build quality. Both cases will support ATX or MicroATX motherboards.

Top Computer Cases for a Trading Computer in 2018:

Power Supply

Power Supply

Power supplies have become very standardized with the different outputs. So as far as compatibility, you don’t really need to worry about that. The motherboard has a 24-pin power connector and an 8-pin for the CPU and on a microATX motherboard its 4 pin for the CPU. The connectors for the hard drives are standard SATA power connectors and the case fans are 4 pin power connectors.

Brand? There is one and ONLY one brand to consider – SeaSonic. I could spend an hour telling you all the benefits, but I’ll keep it brief! SeaSonic is an actual manufacturer, most of the other brands are not – they don’t actually build them, they have another company do it for them.

In the event one does go bad, the 620w version is fully modular, just unplug the connectors and pull the unit out, no need to mess with all the wiring

I wouldn’t go less than a 620w unit, you won’t save much money so why bother going with less wattage? 450w is the absolute minimum I’d recommend, but I don’t like minimums, a little cushion in wattage doesn’t hurt – stick with the 620w SeaSonic.

Top Power Supplies for a Trading Computer in 2018:

  • 620 Watt SeaSonic Bronze – 80+ Certified w/Active PFC
  • 850 Watt SeaSonic Bronze – 80+ Certified w/ Active PFC

Microsoft Windows 10

Operating System

This seems like a no-brainer – Microsoft Windows. I know some are still nervous about switching to Windows 10. I am convinced that Windows 10 is the most stable, robust and easy to use operating system Microsoft has ever created. Not to mention it has proper support for multiple monitors with separate task bars on each screen which Windows 7 doesn’t. Still, if you absolutely need Windows 7 we are still selling it on our trading computers, as long as we can still get it and the hardware supports it we’ll still sell it. 95% of the trading computers we sell are Windows 10, about 5% of customers still opt for Windows 7.

Home vs Pro? Unless you need to connect to a network, just stick with Windows 10 Home, there is nothing in the Pro that traders really need. Microsoft stopped selling Windows 7 Home, the only version for Windows 7 is Pro now.

Best Operating System for a Trading Computer in 2018:

  • Microsoft Windows 10 Home 64-Bit

ASUS Monitor


In order to properly test our trading computers we have monitors from every size, brand and resolution in our testing stations. We’re very familiar with all the different manufacturers.

I recommend sticking with only the major brand names. If I were to narrow it down to one brand it would be ASUS. They offer the best “bang for the buck” when it comes to monitors.

I like 27″ monitors in my own setup, some people prefer 23″ or 24″. Most 27″ monitors are 1920×1080 resolution, which is a perfect resolution for a screen of this size. There are 27″ monitors with 2560×1440 resolution but they are usually much more expensive and setting your screen to this high of a resolution would cause everything to be very small, increasing the scaling in Windows would be the only way to make things more readable. 4K 27″ monitors are also now sold at 4K 3840 x 2160 resolutions, these monitors are extremely expensive and only worth the money if you are into gaming.

Best Monitors for Trading in 2018:

  • ASUS VE278Q 27″ Full HD 1920×1080
  • ASUS VN279Q 27″ Full HD 1920×1080
  • Asus VS239H-P 23″ Full HD 1920×1080

Monitor Stands

If you’re using from 1 to 3 monitors in your setup I would just use the stands that come with the monitors. With four monitors I would us a quad stand, 6 monitors a hex stand. 8 monitors I would use two quad stands and 12 monitors two hex stands.

I like free standing monitor stands – these rest on their own base. The other type use a clamp to secure it to your desk. The stands we sell on our site are all free standing. We have dual, quad and hex stands that support up to 27″ screen sizes.

Input Devices

I’ve been using Microsoft’s Natural Ergonomic Keyboard for over 10 years now. This is my favorite keyboard! The keys are slightly split in the middle to provide a more natural position for your hands. There is a cushioned palm rest and contoured keys.

Best Keyboards for Traders in 2018:

  • Wireless Microsoft Natural Ergonomic Keyboard 4000
  • Wireless Logitech Desktop MK320 Keyboard & Mouse Combo

I use a 3M Ergonomic mouse, I’ve been using it for 12 years now. I’ve went through 3 of them now and they get pretty heavy use so I believe their reliability and build quality is pretty good. I am on my computer for 8 to 12 hours per day, nearly 7 days a week and this mouse has helped me prevent excessive repetitive strain in my wrist. I admit, this mouse is not for everyone, it’s design is a little strange and it’s hard to get used to. If you get tendonitis in your wrist/forearm, this mouse might help. If the design is just a little to unorthodox then stick with a standard mouse.

Battery Backup Cyberpower

Battery Backup

During a storm all it takes is for the power to go out for a split second and you’ll lose whatever was actively running on your computer. A good battery backup helps with this, it will give you enough runtime power to allow the safe closure of open files and shut down of Windows. Also, it prevents power surges and keeps your pc safe. We always recommend CyberPower brand, they are sold in different wattages, the largest will give you more time during a power outage. Keep in mind if you plug in more than just your computer tower it will cut into how long the battery will last, if you have an array of monitors hooked up you won’t get too long on backup power.
