It's time I decided to test the waters in the market making area. Though I focus more on trading alone, I thought of giving it a try.

This article is all about Hummingbot; a great open source project for HFT market making and Arbitrage.

Disclaimer: I am not affiliated or sponsored by Hummingbot to write this article.
I (or hummingbot) is in no way responsible for any loss which may occur to you because of the wild market, and in case something terribly goes wrong, which is well beyond anyone's control (like markets dumping more than 40-50% in days and stuff like that)
I'd urge you to do some research about market making, understand how market making bots work, and then understand some advanced concepts to actually profit our of this market. If you are interested, please do some research before starting off with any market making bot.

A few points to consider:

For consistent market making, make sure to go with this setup only if you have a high speed uninterrupted internet connection and uninterrupted power supply. I have no such issues, hence I proceeded with this setup.

Windows installation is easy/hassle free
Linux installation can be done via Docker as well
You can Deploy the bot on cloud to run 24x7 (I have not tried that yet)
Mac installation is also pretty easy and straight forward.

In my case, I'll be using my laptop which is having Windows installed in it, to set up the Pi.

A word or two about Raspberry pi: It is a cheap microcomputing device, having all the necessary hardware required to run a full fledged desktop computer; which costs a fraction of an actual computer (You can get is for less than $100. I got mine for around $75 using a deal from an online eCommerce site along with all the accessories.)

Check more about it the device here: https://www.raspberrypi.org/

My model is the latest Raspberry pi 4, but with a 4 gb RAM edition.
8 gb was out of stock for sometime in my region, so I settled for the 4 gb edition, but it works absolutely fine and you won't notice any difference unless you are running too may instances.

Before you proceed, please have a look at the original blogs by Hummingbot:

We will be following that only, but with a workaround of the issues which came up in my case.

In case you have any issues, feel free to check out their discord page: https://discord.hummingbot.io/
Their team is helpful and one person by the name Sigit took time to look into my issues to try and help me out. If you are reading this, thanks for your time :)

Setting the Raspberry Pi up via SSH:

Note: If you have access to an external Monitor, Mouse and Keyboard, you can skip connecting your Pi via the SSH. In that case, simply load the OS using Pi Imager on SD card, connect the HDMI with monitor, connect keyboard and mouse with the Pi, and you are good to go!

I'm not having any external monitor since I'm out of my hometown, so connecting it via SSH to be used with my laptop was my only option.

Software Pre-requisites:

(In my case I had windows on my laptop, but feel free to download the relevant packages if you are using Mac or Linux)

Putty (for connecting to the SSH) (https://www.chiark.greenend.org.uk/~sgtatham/putty/latest.html)
Real VNC viewer on your laptop. (https://www.realvnc.com/en/connect/download/viewer/windows/)
VNC server on your Raspberry pi (coming to that later)
Pi Imager on your laptop (https://www.raspberrypi.org/documentation/installation/installing-images/)

Hardware Pre Requisites:

Raspberry pi (of course you need that LOL)
Memory card (high speed will be preferred)
USB type C charger ( 3 Amperes recommended)
Micro SD card reader (USB/SD card reader)
Optional (recommended) : Get a box with a fan in case you want to run it 24x7, otherwise the Pi may get damaged because of heat.
Optional: LAN cable (because I'll directly connect it with Wifi. I was not able to find the IP address of the Pi using LAN, hence I connected it with WiFi)

Step 1:

Download the 64 bit Raspbian OS (32 bit will have a lot of issues with installation, so make sure you download the 64 bit OS only. Currently the 64 bit version is in beta.)
Link: https://www.raspberrypi.org/forums/viewtopic.php?t=275370

Step 2:

Open the Raspberry pi imager on your laptop, and select the "Use Custom.img" and load up the img file you downloaded.
In my case it was: 2020-05-27-raspios-buster-arm64.img

Plug in the SD card and proceed with the "Write option"

Skip from step 3-8 if you are using external monitor with keyboard and mouse to control your pi

Step 3:

create a blank file (For windows user: open cmd, type in: echo>E:\ssh -> It will create a new blank file without any extension, with the name: ssh)

If your memory card is in some other drive, use that corresponding drive letter in place of E:

Or simply create a blank file without any extension, having the name: "ssh"; and save it in the Boot section of the memory card.

This will enable Raspberry Pi to open up SSH connections after boot.

Step 4:

If you want to connect SSH over WiFi (recommended)
(I connected via WiFi because I was unable to find the IP via LAN cable because of some unknown technical reasons)

Open Notepad++, create a config file <wpa_supplicant.conf> and save this in the Boot directory of the SD card:
(if it's E:/ , just save it under E:/)

ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
update_config=1
country=«your_ISO-3166-1_two-letter_country_code»

network={
ssid="Enter your Wifi name"
psk="Enter your password"
key_mgmt=WPA-PSK
}

Make sure you name it wpa_supplicant.conf (and don't save it as a text file else it won't work)

Step 5:

Remove the card and plug it in the Pi and power it on.

Raspberry pi will connect to wifi automatically if the above steps are correct
Now make sure the system from where you will connect is connected to the same wifi.

Step 6:

Open your router login page: (usually: http://192.168.1.1/), and I am assuming you are not using mobile hotspot, or any public Wifi in this case.
Note: If you are using mobile hotspot, try using an external third party IP Scanner tool and it should work fine and show you the Pi IP address.

Find your raspberry ip address.

In my case it was something like this:

Step 7:

Open Putty, type in: pi@(raspberry pi ip address) in the host name and keep port as 22.
example:

At this time, the Pi should get connected to the SSH and you should see something like this:
Ignore the "inactive" status as it is coming after I connect my Pi to the VNC. May be some bug somewhere.

Step 8:

Note: 64 bit OS is still in beta stage, so the VNC server will probably display a blank screen when you connect. This is still an unknown bug, but there's a workaround for that

Follow the below steps:

sudo apt update
sudo apt install tightvncserver

This is required because 64 bit OS on Rpi is still on beta
and they don't natively support RealVNC server yet. (I was getting blank screen error, and dug up the possible fixes when I came to know about tightvnc)

tightvncserver -geometry 1280x720 (you can change your config if you want, but it will create new servers on a different port)
In my case I' using tightvncserver -geometry 1920x1080 instead.

(Set password, no need to set view only password.)

Now open Real VNC,

connect with: :1

And if it connects successfully, you can see the Raspberry Pi Desktop successfully.
