I used GenericCSVData to add my own data with the following dtformat: ('%d.%m.%Y %H:%M').
Even if I add params=(('calendar', NYSE_2014), ...) [within GenericCSVData] and cerebro.addcalendar(NYSE_2014) the system is still buying on holidays and at night.
In https://www.backtrader.com/docu/dataautoref.html I read that for GenericCSVData is no default calendar set. But I should be able to set one through params or cerebro, right? If it's possible then I got some bug in my code.
