Doesn't work standart strategies.

Very strange, can you try running a backtest over the commandline instead? That will give more information. Instructions are here: https://forum.gekko.wizb.it/thread-57581.html

Now it works (command line and web). I can't understand logic.  I install/update additional packages and modules for using (https://github.com/xFFFFF/Gekko-Strategies).  I also did

Code:

npm install

instead of

Code:

npm install --only-production

 
Maybe it helped me. I can't catch the moment what has solved the problem.
