I wrote a very simple code “when MACD histogram is positive and over MA buy 1 share” I set the backtest to start on May 7th. this screen clearly shows it starts on May 7th but I get the Buy/Sell arrows only starting the 14th of May. Anyone knows why?? Here is ascreenshot with some explanations I added https://www.screencast.com/t/iGI4uWHfXhi
