How you can get began with the LEAN Engine and AWS?
To get began with the LEAN Engine, we might want to have a couple of issues prepared and people are the next:
- A QuantConnect account
- QuantConnect account Consumer ID and Token
- An IBKR account
- An AWS Account and EC2 occasion
- Python and Docker
You possibly can comply with our QuantConnect article to get a way of the general platform and get your account prepared. To acquire the Consumer ID and Token, navigate to your profile settings by clicking the Account icon within the higher proper nook of your display screen.
When there, scroll down till you see hyperlinked textual content that states “Request Electronic mail With Token and Your Consumer-Id for API Requests”, click on and you’ll get an electronic mail from QuantConnect with the data you want. Be sure to maintain this secret.
For an IBKR account, navigate to their landing page and click on the crimson “Open Account” button. Then, comply with by their guides and UI to have the account verified and arrange. Be sure to know your Username and Password as we are going to want them.
To arrange your Amazon Net Providers (AWS) account you may comply with this blog post. In the case of spinning up an EC2 server, you may decide location as proven within the weblog publish, and an Ubuntu t2.small occasion needs to be sufficient for this text.
One necessary element is to provision no less than 50GB or so of reminiscence to your EC2 occasion because the docker containers that LEAN makes use of are very cumbersome and never nicely optimized for measurement.
Within the following part, I’ll present you how one can arrange Python and Docker.
How you can arrange your AWS cloud server for the LEAN Engine?
To arrange your cloud server for the LEAN Engine you’ll need to carry out 5 steps that are the next:
- Create a Consumer
- Set up Docker
- Create a Python digital setting
- Set up LEAN
- Configure LEAN Engine
It’s all the time good to begin with updating and upgrading your contemporary servers as they’ll usually have new safety updates to be made. To do that, we run:
$ sudo apt-get replace && sudo apt-get improve
After this has been accomplished, we transfer on to create a brand new consumer. I’ll name the consumer “algotrader” however you may select any identify. To create a consumer, we write:
Then, you can be prompted to fill in some details about your consumer, you may maintain most issues clean or as detailed as you would like. I’ll maintain most issues clean for this text. We are going to add the consumer to the superuser group:
$ usermod -aG sudo algotrader
Now, allow us to set up Docker by working the next set of instructions:
$ sudo apt set up apt-transport-https ca-certificates curl software-properties-common
$ curl -fsSL https://obtain.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /usr/share/keyrings/docker-archive-keyring.gpg
$ echo "deb [arch=$(dpkg --print-architecture) signed-by=/usr/share/keyrings/docker-archive-keyring.gpg] https://obtain.docker.com/linux/ubuntu $(lsb_release -cs) steady" | sudo tee /and so forth/apt/sources.record.d/docker.record > /dev/null
$ sudo apt replace
$ apt-cache coverage docker-ce
$ sudo apt set up docker-ce
$ docker
As soon as that is prepared, we are going to need to set up the dependencies that we want into our digital setting. However first, let’s create a folder for our most important workspace:
$ mkdir qc-ib
$ cd qc-ib/
I like to recommend having the most recent model of pip on the prepared:
$ sudo apt set up python3-pip
Now, we are going to create a Python digital setting that may comprise all of our dependencies:
$ sudo apt set up python3.10-venv
$ python3 -m venv venv
$ supply venv/bin/activate
$ pip set up lean
Now, we’re able to configure the LEAN Engine. To do that we run:
We have to log into our QuantConnect account by LEAN and pull our initiatives into the server. To do that, we write:
It will immediate you to your Consumer ID and Token that was emailed to you in one in all our earlier steps.
Now we will run lean init once more and it’ll get the Docker picture on our server and begin the setup course of. Be sure to pick Python as your language of selection when prompted. On the finish of this course of, you will notice two new issues in your listing that are the lean.json
file and the information
folder.
As soon as that is carried out, you may run this command to drag your scripts:
Good! Now we have our server working and the LEAN Engine pumping, now let’s join IBKR to it.
How you can run a bot on Interactive Brokers with LEAN Engine?
To run a bot[1] on Interactive Brokers with LEAN Engine, all that you must do is begin your bot undergo the prompts that may ask you a couple of questions, and get it going. To take action you write:
$ lean dwell 'QC-SCRIPT-NAME'
[1] In the event you don’t know how one can code a QuantConnect bot, learn this article first.
Though this works, it does require you to have a subscription to IBKR information feeds and related. For the aim of this text, I’ll request delayed market information and run the next command that may reply these prompts straight:
$ lean dwell "QC-SCRIPT-NAME" --brokerage "Interactive Brokers"
--data-feed "Interactive Brokers"
--ib-enable-delayed-streaming-data true
--ib-user-name yourusername
--ib-account youraccount
--ib-password yourpassword
Take notice that it will seemingly require you to have 2FA on IBKR disabled or solely be utilizing the cell phone model of it. You are able to do this reconfiguration inside your IBKR account.
In case your 2FA and credentials for IBKR had been appropriate, you will notice the bot working and exhibiting its logs. In the event you replace your script, you’ll need to run the pull command once more to get the up to date model. Don’t neglect to cease the bot earlier than pulling.
