      I've got headers on True but it seems to only ignore the first header and read 'Date' as an actual data

        I didn't try it myself, but probably the following may work:

        class MyGenericCSVData(bt.GenericCSVData):
            def start(self):
                super(MyGenericCSVData, self).start()
                if self.p.headers:
                    self.f.readline()  # skip the second header (the first one was skipped in GenericCSVData start method)
        
        class MyGenericCSV(bt.GenericCSV):
            DataCls = MyGenericCSVData
        

        Thanks
        Vlad

          The subclass from @vladisld does for sure work.

          You may also read the file with pandas.read_csv, skip what you need and pass it to Cerebro as a PandasData feed.
