problem when GenericCSVData uses fromdate,todate but no data in date range

  • T

    Hi,
    next () method seems to crash in a scenario when loading a data using GenericCSVData and there is no valid data in the csv file for the requested date range specified in fromdate,todate .
    in this case, the ticker is loaded with empty lines (since there is no OHLC data for the date range), and generates the below output:

      File "autotrader.py", line 80, in run
    cerebro.run(runonce=False)
  File "Python35\lib\site-packages\backtrader\cerebro.py", line 1127, in run
    runstrat = self.runstrategies(iterstrat)
  File "Python35\lib\site-packages\backtrader\cerebro.py", line 1295, in runstrategies
    self._runnext(runstrats)
  File "Python35\lib\site-packages\backtrader\cerebro.py", line 1619, in _runnext
    self._brokernotify()
  File "Python35\lib\site-packages\backtrader\cerebro.py", line 1357, in _brokernotify
    self._broker.next()
  File "Python35\lib\site-packages\backtrader\brokers\bbroker.py", line 1230, in next
    self._get_value()  # update value
  File "Python35\lib\site-packages\backtrader\brokers\bbroker.py", line 446, in _get_value
    dvalue = comminfo.getvaluesize(position.size, data.close[0])
  File "Python35\lib\site-packages\backtrader\linebuffer.py", line 163, in __getitem__
    return self.array[self.idx + ago]
IndexError: array index out of range

    Any advise ?
