@knolch said in Plot doesn't show up when running the code: I will not use Spyder now for developing and testing my trading strategies but do you have any recommendations what I could use instead? I mean IDLE works but it's very uncomfortable. Which Editor are you using for backtesting? Apparently people like PyCharm for which a Free Community edition is available. https://www.jetbrains.com/pycharm/ Unless you are comfortable with vim or emacs and don't mind using a standard shell (which for all intent and purposes happens to be bash these days)
