Hell yeah,

I've got a workaround. In the previous post there was a little mistake from me - nvm.

From the beginning:

1. I've struggle with lection 34. Backtesting Strategy & Plotting result because there is a deviation between the tutorial and reality on Ubuntu machine.

2. Everything else from the tutorial on Udemy was closely perfect.

3. For you all I've gathered all the informations from the video AND the MontrealTradingGroup Github-Repository:

wget https://raw.githubusercontent.com/MontrealTradingGroup/deployPython3VM/master/python-pip3.sh 
sh python-pip3.sh 
pip3 install virtualenv --user 
mkdir .env 
virtualenv .env/freqtrade 
source .env/freqtrade/bin/activate 
(.env) mtg@mtgvb:~/$ deactivate 
sudo apt-get install git 
git clone https://github.com/MontrealTradingGroup/freqtrade.git 
cd freqtrade 
sudo apt-get install make build-essential python3-dev 
git checkout develop 
sh ./install_ta-lib.sh 
./setup.sh --install 
source .env/bin/activate 
(.env) mtg@mtgvb:~/freqtrade$ pip install numpy 
(.env) mtg@mtgvb:~/freqtrade$ pip install -e . 
(.env) mtg@mtgvb:~/freqtrade$ python3.6 ./freqtrade/main.py -c config.json
(.env) mtg@mtgvb:~/freqtrade$ python3.6 ./freqtrade/main.py -c config.json -s BBRSI  backtesting --export trades --export-filename user_data/backtest_data/backtest-result.json
(.env) mtg@mtgvb:~/freqtrade$ python3 ./scripts/plot_dataframe.py -s BBRSI ADA/BTC

Then it works!

The clue is to get the backtest-result.json to be generated. The comment I found here from @xmatthias python3.6 ./freqtrade/main.py -c config.json -s BBRSI backtesting --export trades --export-filename user_data/backtest_data/backtest-result.json is sovling the issue.

Thanks all for helping.

Maximal profits to you all.

EDIT:

If somebody got this error:

ImportError: libta_lib.so.0: cannot open shared object file: No such file or directory

This is my work around:

[SOURCE]

1. http://prdownloads.sourceforge.net/ta-lib/ta-lib-0.4.0-src.tar.gz
2. https://sourceforge.net/projects/ta-lib/files/ta-lib/0.4.0/ta-lib-0.4.0-src.tar.gz

wget [SOURCE]
tar -xzf ta-lib-0.4.0-src.tar.gz
cd ta-lib/
./configure --prefix=/usr
make
sudo make install
pip install numpy

If you don't have it installed pip install TA-Lib

If you do have it installed pip install --upgrade --force-reinstall TA-Lib
