The DemaTrading.ai Engine is an open source backtesting Engine for cryptocurrency trading as a part of DemaTrading. The Engine is completely written in the programming language Python. Some experience with Python makes this process easier, however with some effort this project should be runnable for everyone, no matter your experience with coding.

For any questions not covered by the documentation, or for further questions regarding the engine, trading, your own strategies, your algorithms, or just a chit chat with like-minded individuals, you are more than welcome join our Discord server, where we will facilitate whatever need you may have.

There are multiple ways to run our Backtesting Engine. For each way, the installation steps are outlined below. We recommend using Docker to run the Backtesting Engine, but you can also use standard Python.

To make your a life a lot easier during strategy development use a code editor such as PyCharm (recommended) or VSCode.

If you want to run the engine using Docker, you need to install Docker using the steps described here. After installing you need to run Docker in the background.

To run the engine you have to open a terminal of choice and enter the commands described below.

1. This command will initialize a directory containing all the necessary files for running the engine and developing strategies:

docker run -t --rm -v "$(pwd):/usr/src/engine/output" dematrading/engine:stable init

Note: if you are using Windows, please use Windows Powershell to perform this command.

2. To run a backtest use the following command:

docker-compose up

If you want to run the engine using Python, first you need to download Python 3.8.6 by clicking this link. Furthermore, you will have to manually download this repository on your computer. This can be done by either downloading the repository as a .zip file or the recommended way which is cloning the repository using Github Desktop (or something similar). For more information about cloning a repository see this link. To use the engine you need TA-lib, which can be installed using the following steps that correspond to your operating system.

Note: if you're device is running on the M1 Chip by Apple Silicon, please follow the installation instruction described in our docs.

1. Install Homebrew (optional). This can be done by running the following command in your terminal:

/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"

2. Install TA-lib library by running this command:

brew install ta-lib

OR if you you skipped Step 1. you can run this command (requires Xcode12):

pip install ta-lib

1. Download ta-lib-0.4.0-src.tar.gz.

2. Run the following commands:

$ tar -xzf ta-lib-0.4.0-src.tar.gz
$ cd ta-lib/
$ ./configure --prefix=/usr
$ make
$ sudo make install

1. Find your current operating system. This can be found in system settings (either 32-bit or 64-bit)

2. Go to this link and search the page for "ta-lib".

• If you have a 64-bit operating system download: TA_Lib‑0.4.20‑cp38‑cp38‑win_amd64.whl
• If you have a 32-bit operating system download: TA_Lib‑0.4.20‑cp38‑cp38‑win32.whl

3. Open a terminal (e.g. Windows Powershell) and change to the downloads folder:

cd [PATH/TO/DOWNLOADS/FOLDER]

4. Install the TA-lib wheel by running this command:

pip install [TA_Lib-wheel].whl

1. Change to the engine directory by running this command:

cd [PATH/TO/ENGINE/DIRECTORY]

2. Install all other needed dependencies by running this command:

pip install -r requirements.txt

3. Run the engine by running this command:

python3 main.py

To start developing your very own strategy, we suggest reading our docs for more information.

To give you a headstart, we included a sample strategy which can be found in /resources/setup/strategies/my_strategy.py

If you want to create your own strategy just simply copy the sample strategy and change the name of the class to for example 'MyNewStrategy'. Then just change the config.json file in the engine directory accordingly to test this strategy:

"strategy-name": "MyNewStrategy"
