10.2 Benchmarking

可以通过两种方式去跟踪TimeReturn(或者其他指标）和Benchamark

• Observers

  cerebro.addobserver(bt.observers.Benchmark,
  data=benchdata,
  timeframe=TIMEFRAMES[args.timeframe])

• Analyzer

  cerebro.addanalyzer(bt.analyzers.TimeReturn, timeframe=bt.TimeFrame.Years,
  data=data, _name='datareturns')

  cerebro.addanalyzer(bt.analyzers.TimeReturn, timeframe=bt.TimeFrame.Years,
  data=benchdata, _name='timereturns')
